I'm trying to decide how Vic feels about Owen. Like, I imagine he liked the guy because he made Marvel happy, but that means Owen was probably another source of resentment (how come I don't have a hot, famous boyfriend?). And then with the breakup, even though he wasn't on the best terms with Marvel, Owen would still be the ex, so Vic probably has some bristlies deep down that he won't acknowledge. But they're probably cool enough.
Yay for being friends with Jack.
And Vic is probably cool with Steven because of those things you said. Spotlight-stealing siblings are the worst.
He'd probably tolerate Cal's more hyper moments, but not really cut him enough slack to be actual friends without a good reason. If Vic ever gets catty, it would probably be with someone like Cal, rather than Billy. Snarktastic!
