Same! I thought that Bela was a hoot, she was just fun every time she turned up... I was really sad when she died, too, and I think that her story was among the more tragic of the show.
And while I'm sure Misha is a very nice person, and I know that he does some great charity work... he was in a film the existence of-which I'm not especially happy (which, I realize, is a me-thing) so no, I don't do the fangirl shuffle over him either. *goes in to Witness Protection*
Yes. THIS. So much this! :D
I'm of the general view that Sam and Dean are written and acted as being straight as well- I think that Dean and Cass can play off of each other well, but I never really saw where the sexual attraction was supposed to kick in with them. And the fact that Wincest is a thing... it weirds me out, more than a little. Like.. just why, people? They're related! Incest isn't sexy!
I'm mostly with you on the ship front too, except that I accidentally (like, my words after the episode were "Aww, they're strangely cute together, that'd be really interesti-- DAMN IT") found myself (for the all of two or three episodes it was of relevance) shipping Cass and Meg. But I haven't shipped any duo/trio before or since- so long as they're hunting, I actually kind of prefer them romantically unattached. *gets massive surgical adjustments to face in addition to going in to Witness Protection*
