I'll look it up when I get home from work, but the previous day there had been a kerfluffle about a fan being told by con staff that she wasn't allowed to ask questions related to slash to Jensen, and also because someone did ask Misha Collins about it (he seems to have handled it well, as he generally does. Apparently he mentioned queerbaiting and facilitating gay weddings.) There were a lot of people on Tumblr Sat. talking about how embarrassing it was for people to ask shipping questions, etc. I think the first few words of her question could possibly imply that she thinks Dean is canon bisexual, and Dean being bisexual is a common trope for Dean/Cas shippers. Not Wincest shippers. I don't know why.
