With the impending release of Civil War and Vision #7 it's a good time to ask: why do you think the Vision/Scarlet Witch relationship has been so popular? (I know you've said it would be pointless to get them back together in the comics, and I agree - but it's hard to think of one of them without the other.)
I think it was popular because it was the most engaging super hero soap opera of its day, the precursor to stuff like Scott and Jean or Rogue and Gambit.
