ALLEGIANT SPOLIERS I'm Tris. Yeah, I know. I'm not dead. I would've been if it weren't for my daughter, Rosie. Indeed I am alive, but dead to everyone at the same time. Will someone find me?

Even ten years after scattering Tris's ashes, Tobias is trying to figure out how to live life without her. He has professional success and still keeps his close circle of friends, but he still struggles with her ghost. Christina shows up at his apartment late one night, with Tris in her car, and he prays that it's a dream. Because losing her again could destroy him. Xpost from AO3.

*SPOILERS* "My heart thumps out of my chest. I catch a glimpse of bright blond hair, too low down for me to see who it really is. Think straight, man. Get yourself under control. She's dead. Dead. I pull open the door, and my mouth goes slack. 'Tris,' I exhale, 'It's you.'" Post-Allegiant, not an alternate ending. Believable explanation. ON AN INDEFINITE HIATUS!

Alternate ending one-shot of Tobias and Tris, then a short epilogue in which they have a family of their own. A little happier than the book ending.
