One-One

• The Snow Car is his favorite car because he met Tulip there (also he was stuck there for 30 years). But from the evidence from the Snow Car clip he maybe slowly forgetting events only for small things (like the rock) to remind him of said events.
• One-One can’t eat, but if he did his favorite foods would be popcorn & soda (Movie Theater Car) and chocolate bars ( Minecart Car), but he would hate coconut (again Minecart Car).
• One-One will slowly realize that denizens have their own desires besides helping passengers (ex. Lake) and if they desire to leave the train he will assist them.
• When he was One, he was very cold and didn’t bother explaining how the train worked to passengers (luckily denizens like, Kez, explained how things went). After, Tulip left he made the videos to help explain what the passengers must do to get home. This both got passengers off the train quicker and saved many lives.
• The reason he was stuck in the Snow Car for so long was because: both passengers and denizens didn’t notice him in the snow or on the snowman (woman or person) body, he was out exploring the car, or he was to busy collecting junk for his secret stash. Bonus: Amelia purposely put him on the snowman (woman or person) body to humiliate One!

The Cat

• As great a business woman she is The Cat doesn’t think things through ex: turning Ryan, Min-Gi and Kez to the bug police, never going back for Simon, and trying to trap Tulip in her memories. She did help Kez after realizing the Old West Car denizens were going to execute Min-Gi and Ryan for something so stupid as a tea stain, she believed that the ghom killed Simon and never looked back (she deeply regrets that now), the Conductor just wanted One-One not Tulip, after Tulip escaped and the Conductor wanted her as well The Cat realized how badly she messed up.
• I doubt she’s one of the first, but The Cat is one of the oldest denizens on the train ex: knew there was another conductor before Amelia came, hasn’t taken a vacation in 150, said the Chat Chalet Car has been dry for centuries.
• The Cat owns many businesses and cars ex: The Cat’s Car, Le Chat Chalet Car, The Lucky Cat Car, the doughnut-holer business, the tea shoppe in the Old West Car, the list goes on!
• I don’t think The Cat knew the Apex were wheeling denizens. She knew they were ruining cars ( especially hers), but had no clue about the deaths.
• The Cat’s hoarding is to cope with her insecurities and failures. When, she finds out about Simon’s death her collection will only get worse.

Randall

• Randall makes a fortune out of the doughnut-holers, but the fortune is mainly trash. His main types of payment are flowers and gum.
• I think Randall is unable to be killed. From what was shown in Le Chat Chalet Car he can be frozen or boiled (and eaten) and still be alive. The dude’s immortal!
• The Cat always brings Randall with her just incase she needs a hand in one of her money making schemes. Mainly, because she knows good and well that both passengers and denizens are indifferent towards her due to past schemes, but everyone loves Randall.
• When, The Cat and Frank leave Le Chat Chalet Car, Randall (or a part of him) askes to stay because of his love of the snow. The Cat allows it, but tells Randall to make sure if passengers or denizens come to the chalet they have to pay to stay. too bad the payments are usually gum, flowers, rocks, and other useless things. But, ever once and awhile Randall gets paid money, CDs, jewelry, and other shiny trinkets.
• Continuing with the last headcanon - Randall takes good care of the chalet when The Cat is away! He makes sure the pantry is stocked with food and non-Randall water, invites guest to snowball fights, and gives them doughnut- holers as guest gifts. Because of Randall the Car becomes popular, and why The Cat allows him to keep it open.

Atticus

• After hearing the news of what the Apex did to the Unfinished Car, Atticus has reached out to other cars to stop the Apex so they wouldn’t damage passenger/denizen relationships.
• Atticus was the runt of his litter and abandoned at a young age. Atticus becoming king is the classic orphan-becomes-king story.
• Atticus does check-up on One-One when he gets the chance. The two do talk about Tulip and how they miss her.
• Atticus created a tulip field (mainly orange and yellow) in honor of Tulip for saving Corginina and returning One-One as conductor.
• Stops calling Irwin, ‘Ugly Irwin’, and encourages the other corgis to stop it too. Because, it’s rude to make fun of someone’s appearance.

Alan Dracula

• One created Alan Dracula to be unpredictable on purpose. For passengers who expect something to happen to realize nothing is set in stone. Now, One-One can’t even predict what Alan Dracula will do next.
• Alan Dracula was in The Party Car with Min-Gi, Ryan, and Kez (based on the deleted scene) and was the only partygoer to hear Ryan and Min’s song.
• Alan Dracula still has the sunglasses Jesse gave him.
• Seeing as Alan Dracula was born before Amelia took over the train he is most likely 30+ years old at best.
• Lake and Jesse were the only passengers that stayed with Alan Dracula the longest since few understood him and his love of grass.

Tuba

• All of Tuba’s children are named after brass instruments. We know about Bugle, but I think the others would be named: Trumpet, French Horn, and Trombone.
• Tuba’s satchel was a gift from her late husband.
• Tuba’s favorite food is pineapple since she ate a lot in the Jungle Car episode.
• Tuba sang a ton of lullabies for her children and Hazel. The most popular one was the one sung in the show.
• Once, Hazel comes to Earth she’ll make a grave for Tuba to remember her by. The rest of the Infinity Train passengers (Tulip, Lake, Jesse, Grace, Min-Gi, Ryan, Amelia, One-One- I’m gonna end it here, but it’s the rest of the denizens) come to show their support.

Kez

• After what happened in the Art Gallery Car, Kez leaves signs and directions to allow the passengers and denizens to solve the puzzle easily. But each time she returns the signs go missing or destroyed!
• After, making things up to the denizens she’d angered Kez became friends with them minus Judge Morpho. Kez doesn’t focus on that really since she has friends now.
• Sometime after Ryan and Min-Gi left, Kez and Morgan decided to make a lounge area that dedicates Jeremy, Ryan, and Min-Gi.
• Kez spent a year away from Morgan after what happened to Jeremy. That gave her enough time to travel other cars, and (accidently) caused a lot of damage.
• Kez rarely leaves Morgan now since they made up, the two really missed each other. When, Kez does leave it’s usual for a couple of hours at best.

• The two either met at college or at a Chicken Choice Judy concert (I believe the second part because of irony).
• After the divorce Andy stayed with a friend who’s still in a bachelor stage. The friend is still close to Megan and Tulip and invites them for dinners a lot.
• Megan once begged Tulip to get a normal flavored cake for one of her birthdays instead of onion. Tulip agreed to get vanilla cake, but only if she got an onion one. Turns out everyone liked the onion one better, and Megan never told them the cake had onion in it.
• The reason the Olsen house is so far away from any other house because Megan and Andy built it themselves. They were told it was going to be a neighborhood, but the company went into bankruptcy before other houses could be made. They didn’t mind though.
• Their happiest memories together was when they were on road trips with Tulip. They tried to get her into Chicken Choice Judy, but Tulip would only listen to ‘Word Up’ and songs from animated movies.

Mikayla

• Mikayla is a music nerd: jazz, hip-hop, low-fi, classical, she loves them all. When Tulip gets back from the train she introduces her to Chicken Choice Judy. Tulip realizes after hearing 'Train to Nowhere’ that they were passengers too.
• Mikayla is the oldest of four siblings. Whenever Tulip visits her, it makes her both wish she had siblings and thankful that she’s an only child.
• When Mikayla got the news of Tulip missing, she believed that by talking about Tulip’s parents being divorce she caused her to run away. Mikayla blamed herself, but Tulip reassured her it wasn’t her fault.
• Mikayla is an outdoorsy kind of person and prefers going to parks, festivals, beaches- basically anything not indoors. Maybe that’s why she hates video games because their almost always inside.
• I see Mikayla as a hipster. But she won’t like or dislike something because it’s popular. She’ll give things a chance before she decides she’s not into it.

Nathan Cosay

• After, witnessing Jesse going back on the train then returning Lake, Nate wonders if one day if he’ll ever get on the train. Jesse and Lake do their best reassure him that the train is there to help passengers learn, secretly they hope it never happens.
• Nate loves animals (mostly dogs from his t-shirt from the last episode). After, Jesse and Lake talk about Alan Dracula, Nate so wants to meet the magical deer.
• Nate was inspired by Jesse to swim. Every chance they get the two use the lake to practice and goof off.
• Lake has a stupidly large soft spot for Nate. She’ll/They’ll help him with homework and win bets against Jesse. Jesse doesn’t blame Lake for it since Nate is a good kid.
• I don’t know why by I see him as a s'mores lover (maybe because I’m craving some right now). Like every campout with the family he eats the most s'mores and never gets sick!

Jesse’s ex-friends

• The group is most likely juniors as Jesse is a freshman.
• Are the bullies at their school and nobody knows why a nice guy like Jesse would hang out with them?
• When Jesse disappeared, they were blamed for it along with Nate’s broken arm.
• They’re most likely to dropout or get kicked out of school.
• I refuse to give them names because they are bullies.

Jesse and Nate’s Parents

• Their names are Alex and Madeline (based on the writers’ names).
• Have a love of the great outdoors and are glad Jesse and Nate (and Lake, Tulip, and Hazel) share in their love of nature.
• The mom is a huge Chicken Choice Judy fan and got Jesse into them.
• The Dad works at a sports store that sells a lot of camping equipment.
• After, hearing how Jesse got on (and off) the train, they worry that the train will come back. So, they put Jesse, Nate, and Lake in therapy as a safety percussion.

Grace’s Parents

• Grace’s mom grew up poor and as soon as she got married to Grace’s father she never looked back. They did visit them during trips to England, but they were brief visits. Grace barely remembers them, but she misses her maternal grandparents.
• Their names are Kirby (After Grace’s voice actress) and Justin.
• After, Grace went on the train, her parents realized they knew nothing about their daughter not even her favorite color. Grace’s caretakers ended up giving more information to police than them.
• Grace’s father holds some sort of government position as seen in the 'Origami Car’ episode they were having dinner with an ambassador.
• I believe they came from loving families and as an ironic twist were neglectful towards Grace.

Simon’s Parents

• I think his family ran a funeral home and there were many deaths in his family.
• Simon’s mom has zero fashion sense due to the socks and sandals thing (ugh).
• Not gonna lie this is all I have on Simon’s family, since there wasn’t much to go on from the beginning.

Apex Kids

• Let’s be honest the families of the Apex kids are going to hate Simon and Grace! Not only were the kids missing for years, but they were raised to be murderous cultist and abused! And no amount of tragic backstory is gonna make what happened okay.
• Even after Grace leaves the train she will have zero contact with the former Apex members because she wants them to grow up and be better than her and like I said above the children’s families hate her.
• After, Lucy gets off the train her parents try to get her a glass eye or donor. Lucy refuses saying it’s punishment and a reminder of the things she did on the train.
• Because of the Apex some denizens are terrified of children passengers.
• The first act of dismantling the Apex was them cleaning up the Mall Car.

Ryan and Min-Gi’s Families

• Min-Gi’s mom is a nurse and his dad banker (which is why they wanted Min-Gi to go into finances). Ryan’s mom is a daycare worker, and his dad is maybe a ferry worker (from the ferry joke he made in the Twin Tapes episode).
• Ryan’s siblings are named Allison (Oldest sister), Naia (older sister), Izaac (younger brother), and Nick (youngest brother). The names are based on their voice actors and writers. We know Ryan’s mom’s name is Yui, Min-Gi’s mom’s name is Niki (after her voice actress), I had no idea what to name the dad’s since they share the same voice actor.
• Ryan’s siblings know about his magazines (check the deleted scene to understand) and find it hilarious that their parents thought the magazines were Min-Gi’s.
• Ryan’s younger brother wears glasses when he’s older making him and Ryan the only glasses wearers in their family.
• Mrs. Park and Mr. Akagi are the cooks of their families.
• Min-Gi’s mom was the first one to know and accept Min-Gi’s and Ryan’s relationship. When the boys went missing it hit both families hard; so, Mrs. Park worked longer hours at the hospital to distract herself. Since season four takes place during the 80’s and it was the time of the HIV/AIDS crisis the hospital would’ve been packed with patients, who Mrs. Park treated. One of them I’m gonna call Whizzer (Falsettos reference) ended up in Mrs.Park care and later befriending her. Whizzer reminded her of Min-Gi and Ryan and was around their age and became like another child to her. Over time Mrs. Park learns of Whizzer history about how his parents didn’t support his dreams, was disowned and abandoned by so-called loved ones, and ended up with HIV; this makes Mrs. Park wonder if she was supporting Min-Gi on what he wanted to do with his life. Whizzer’s condition worsens; Mrs. Park stayed with him until the end. The last things Whizzer told her was he wished to have met Min-Gi and Ryan and that he hoped they would find them soon. Later, -like a week or something- Min-Gi and Ryan return from the train, Mrs. Park accidently finds out about their relationship. When, the two leave to go to New York, she tells them she accepts them. At first, they thought she meant she accepted their dream of music (which she does), but she was accepting them as who they were. Every year on Whizzer’s birthday Mrs.Park goes to his grave, and Min-Gi and Ryan go with her. WOW! I did not mean for this to be that long, now I need to write a fanfic of this.

Ryan’s Ex-Girlfriends

• Their names are Lindsay (Disco), Megan (Punk), and Sofia (Earthy). Again, their names are based off people who worked on the show.
• Ryan also dated two guys while he was on the road who were a goth and a prep.
• The Disco girl works at a roller-skating ring, Punk girl works at a tattoo parlor, and Earthy girl is either a florist or owns a fruit stall at a farmer’s market.
• Earthy girl tried to return the van after Ryan and Min-Gi returned from the train, but Ryan let her keep it. During the months the boys went missing Earthy girl befriended Ryan’s sisters.
• Ryan is still friends with his exes, the reason why is because Ryan was nice to them, and they had dated worse. They love telling Min-Gi embarrassing dating stories.

Jeremy Bradford

• Jeremy was very close to mother and sister growing up, so their deaths deeply affected him. In fact, Morgan reminds him of his mother and Kez reminds him of his sister.
• Probably opened up a hat store after getting off the train.
• Jeremy befriends Min-Gi and Ryan, the three bond over how they miss Kez and Morgan.
• After getting off the train the first person he contacted was his roommate Keith who missed him the most while he was on the train.
• I don’t know why, but I think he’s British or maybe he’s from Florida.

Cassette Girl

• Can’t decide to name her Kari or Annisa (named after voice actor and artist).
• Works at a music studio as an intern and helped Chicken Choice Judy get their music out, and later became their manager.
• She probably is a huge sushi and coffee fan. Every year on her birthday Min-Gi and Ryan take her to a new cafe or sushi place.
• Is street and musical smart.
• Ryan and Min-Gi tell her about Kez and the crazy adventures she got them into (not that she’s a bell or the train part though). She finds Kez funny and wishes to meet her one day… She does.

Alrick

• Alrick is allergic to nuts so he only eats jam.
• As much as Alrick loves kids, he didn’t want to be a dad. He was fine being a babysitter or uncle. Luckily, Amelia didn’t care for kids.
• From Amelia’s memories Alrick and her loved trying new activates like: dancing, cooking, they might’ve even tried bungee jumping, as long as they were together.
• Alrick was the cook of the two, except pancakes for some weird reason they’d come out burnt to a crisp or soupy on the inside. Amelia will always make the best pancakes.
• The day Alrick died it was a rainy day when he was dirt-biking with his friends. When, it rained on his funeral it drove Amelia even more because both used to love rainy days.

Extras

• Ryan befriended the lesbian couple at the party in 'The Twin Tapes’.
• Jesse befriends everyone on his swim team and theatre club. It takes Lake awhile, but she/they do make their own friends.
• Tulip befriends other ex-passengers at game design camp.
• The girls in Grace’s ballet class would later find out that Grace lied to them. But, by the time they do Grace dropped out of their class making them look like fools.
• After, Amelia disappeared friends and relatives spent years trying to find her.
