That Supernatural is celebrating it's 100th episode with Dean doing something stupid tonight. Followed in short order by Sam doing something stupid, I'm sure. Those two are pretty but sometimes I'm just not sure they're playing with a full deck.
And over on The Vampire Diaries, Elena and Jeremy's uncle waltzes into town looking exactly like one Julian Sark: Sexy, Magnificent Bastard. Also, since it's The Vampire Diaries, about a hundred thousand other things will happen. This has to be the most exciting show ever. Seriously, more happens in a single episode of TVD than in a whole year on most shows.
