Summary
Months after the Krang invasion, Donatello begins to experience severe shell irritation. When tests reveal leftover Krang matter lodged deep in his shell from the Technodrome explosion, Leo and Draxum perform a delicate extraction procedure to save him. Recovery seems promising—until Donnie collapses weeks later and begins coughing up blood.
After an emergency evaluation, Draxum delivers the devastating diagnosis: a rare, aggressive form of cancer, likely triggered by the Krang residue. As Donnie undergoes harsh treatment, Leo—driven by guilt, love, and fear—digs into his medical training, determined to find a cure. He refuses to let his twin slip away, even as Donnie weakens by the day.

Summary
"Donnie braced a hand against the slick tile, his chest tightening as his breath stuttered. His circuits hummed, buzzing under his skin as though his own tech was betraying him. He shut his eyes, but that only made it worse.
Leo, broken.
Leo, gone.
Leo, almost never coming back.
His hand trembled as he reached out blindly, desperate for something—anything—to ground himself. His fingers closed around a bottle. Not his usual shampoo. Not the generic citrus scent he always used. No, this one was his twin’s"-or-
The smell of Leo's soap brings comfort to Donnie, but having his actual twin comfort him might be even better
