Y'know, it's quite probable that the Big Date won't end in romantical shenanigans--as long as Hanners doesn't drink/takes her meds/doesn't injure Sven, and Sven controls the devil in his pants on his shoulder. And as much as I'd love to see a good trainwreck, it would also be nice to see Sven make a friend.
So if he pulls it off...perhaps Hanners will reintroduce him to Marigold? Who, unlike Hanners, is very romantically interested in boys? And who plays WoW, much like Sven secretly does (I think they might even play the same side/faction...?) Could there be adorable awkwardness over the clash of insanely popular but secret nerd Sven and out-and-out insular Marigold?
And perhaps Sven, whom, as Ray of Achewood would have it, is a "breast man", will discover Faye does not have the only set of epic boobs in town?
Whiiiich could also lead to all sorts of interesting drama! Sven is a penitent gigolo who has exes everywhere, some of whom want him back in the sack. Mari has never even kissed a boy before drunkenness and Angus. Angus is dating FAYE and he and Sven will have to Kung-Fu Fight at some point or another. Marigold could worry she was being used to get to Faye! Dora could summon forth Yog-Sothoth out of pure rage! Endless possibilities!
