I can't believe I missed this thread. I love this show! I felt Season 1 was hit-or-miss, but Seasons 2 and 3 were all around badass. And Season 4 so far. . .
Holy. ****. Seriously, I love where they're taking this. It's epic! And, Castiel is such an awesome character. I hope he stays around for awhile. I sorta miss Bella, though. As much as I hated her, she was hot and good for a laugh. And the old Ruby was infinetly better then the new one.
This week, time traveling to meet John and Mary before they get married. And, Sam and Dean's grandfather is Skinner from the X-Files! Apparently, he has some big secret and it ties into how Mary and her friends knew about Yellow Eyes.
