We're already talking in IM but my five are outlined here. Jack no doubt is completely fucking in love with his dog because. dogs. And we have some vigilante shit we're working on re: demons and. stuff.
Steven's more or less his age and they went to school together, and I guarantee you he understands sibling bullshit. He loves Luka, REALLY HE DOES, more than anything, but he's the older brother to a super-wealthy, super-charismatic super-genius so that was rough.
And Vic is prolly also VERY familiar with Owen. Owen and Marvel grew up as besty best friends and then they were the superhero power couple for a few years, and then Marvel impersonated Owen for a while and now they're.. kinda getting to be better friends again but can occasionally be dicks to one another. XD
