HOMG Show, way to break my heart and put it back together over and over again and then break is even more! I seriously was on the verge of tears for half the episode with Castiel and Bobby and Dean and Sam. Oh, my heart!
I totally cheered out loud when Castiel showed up, all badass and angel-killing and saving Sam and Dean, and Zachariah made me so freaking disgusted and angry because he's so fucking smarmy.
Gah, welcome back, show! *snuggles it*
