We had a lot of shows to track this week, but the one everybody seemed to be watching was The Walking Dead. With its second season finale, the show once again entered the ratings record books, thoroughly dominating Sunday night.

Everyone's favorite angel on The CW's Supernatural, Castiel, has been M.I.A. for much of the season—but actor Misha Collins says all that will change soon. Spoilers ahead!

The "government agents investigate strange things" premise has almost become a trope these days, but if you think back a few decades, there was a time when it was the bleeding edge of cool. The year was 1993, and Fox—the little network that could—was still building its reputation. Execs took a chance on a little show called The X-Files, and the rest was history.

As any fan of The CW series Supernatural likely knows, death is rarely the end. Heck, for half the characters on the show, it's usually just the beginning of a new storyline. But, it seems the recent passing of one beloved character could be for real, if the actor who plays him is to be believed.
