so for HEAD HONCHOS, london is the one she'll have known longest since he's the mama's officer. depending on the timeline you have in your head, he could've recommended her for captaincy? he really respects her, would not want to get in her way if she was angry, and thinks she's been improving at being a captain every day.
ren is her killjoy commanding officer, and it's hard for ren to really get along with ANYONE, so we'd have to play that by ear since she's super cutthroat. :| she Cannot with the younger, more naive killjoys that have come in in the last decade, and respects a lady who isn't here for shits and giggles. THIS IS SRS STUFF, GUYS. TAKE IT SERIOUSLY, TAKING A LIFE.
