I know what you mean. I came across some Dean and Castiel hate this morning in a blog. Some people are super defensive that Sam is going to have less screen time in the next couple episodes.

I don't get why they don't trust that Kripke has a plan, and it involves Sam being gone for a bit. I fully trust him to fix the relationship. I'd be mad at him if he didn't. *cuddles all the guys*

Maybe I'm just used to large ensemble casts, where characters aren't in every single episode. ^_~
