Jahan is like LOL well then! I'm good with them being friends! Jahan is every bit as outgoing as James, so he's definitely have a pretty large network of friends, even if Vee, Rem, and Calla are his core peeps :)
Kolya definitely is not likely to ever hurt Sage, so they'd be fine on that front. He's probably stood the test of time by now. So I think a brotherly-sisterly affection would make sense! lol Kolya doesn't really have any qualms about saying what an ass hole he thinks his dad is. Sometimes you really need to see them together to understand that Kolya really means it. There's a chance that's happened over the years though.
