as much as i love rgbtrio found family, and how sweet it is for them to be considered siblings in a fic, i simply don’t believe that they choose to stay with each other post-genloss.
if anything, they probably hate each other.
why would you ever want to be anywhere near two walking reminders of your trauma? why would you want to look at the face that promised it would come back for you, the face that let you get dragged away to your death, the face that cut into your stomach, pulled out your guts, and left you to bleed out?
they don’t want to stay together. they’re forced to.
it’s not like they can go back to their homes; they all probably live in a different state, possibly even country than the mall is in. they don’t have money to travel back home. they can’t afford to be alone though; they need to have another set of eyes watching their backs in case showfall shows up again, and it’s not like they can stay with any of the other cast. they might as well be permanently dead, for all the trio knows.
rgbtrio are brothers, not by the blood they were born with, but bound by the blood they’ve spilled together.
