I actually think both would be great combinations if you're game! From what I know / have seen / read of John so far, I think Val'd take to him easily enough and I think they'd get along pretty well! I... just can't promise John won't wind up unofficially adopted somewhere along the way, which might make their eventually meeting up at some point more exciting. As for Nervous Broad, Val could definitely use some more girl friends and I'd be willing to bet NB could, too. And the more I think about potential CR between the two, the more and louder I hear "fun fun fun fun," so I'm totes game!

Also I'm going to go ahead and shamelessly say you should totally familiarize yourself with BC and that I can totally help if you need help doing that. Just sayin'.
