This is the first episode I've been disappointed in all season. Yes, it is not the only filler episode we've had, but I least felt like most of the others were wrapping up storylines or moving the plot along a least a tiny bit. This one just felt a little pointless, we already knew about Billie's plans for Jack, and Dean not telling Sam the whole truth is pretty old hat, the only new information we get is that Chuck has finally completed his destruction of the other worlds. This really felt like a wasted episode. I don't mean to be negative, I have been actually enjoying most of the season so far, but I really thought we'd be ramping up for the finale by now.
