Summary
Even months after Leo’s out of the prison dimension, Prime still haunts him. The time dilation, the inability to not die- wow. Leo was over 50 now, wasn’t he?
All that time in the prison dimension wasn’t spent getting beat though, no.
Leo just wanted a family. A real one. Sometimes, it feels like Prime is.
Maybe... if he can just find the key, then he’ll finally be happy.

Leo doesn't know how to be a good leader, so he makes a to-do list.

Fuck, they almost got hurt. They almost got hurt because of him."
