You being two years back is the only thing that's made this feel normal, Donnie! You're the only one who hasn't been acting like I can't be trusted to act on my own, like you aren't just waiting for me to- I don't know- get myself killed or something.

[He slumped into his shell a bit, staring at a loose bolt on the floor.]

Sorry for wanting to keep it that way.
