I'm a third way through Tractorbeam and yes, you're right, I'm loving it. XD (it makes me think that every fandom needs a crossover with TBBT because every fandom needs a socially inept theoretical physicist) I'm not familiar with the side characters, but Tom Welling dressed as Superman for Halloween is kind of ironically awesome.

Haha, is that how you got sucked into J2 and subsequently, SPN? I've always wondered about how judging IC-ness and OOC-ness with RPF worked -- and y'know, being consistent in characterization -- but I guess having more flexibility with characterization is part of the appeal?
