Great Joss/Brian K (what does that K stand for btw?) Vaughan interview over at
CBR - but SPOILERS!
I did like this non-spoilery exchange:
JW: And in that vein, quick team-up one-shot: one Scoob and one Runaway. Who would be fun?
BKV: Spike/Molly is too easy, and Willow/Nico is too predictable, so I'm going to go with Xander and Chase; two dudes who would normally hate each other bridging the geek/jock divide with their mutual lack of powers/breathing love interests.
How about you?
JW: Well, my Willow/Karolina fic is a little ... hemn ... derivative, so I think I could rock out a Buffy/Xavin story. They both have a certain distance from the people around them, they're both very focused, and Buffy would be freaked out by Xavin's powers every single time. "Aah!" Every time. Gold.
I return to my earlier theory - BKV and Joss are secretly twins who were separated at birth!
