DwtS: And that's why they don't call him "Bill Nye: The Dancing Guy". Of course given how long he coasted, I doubt Gaga's going anywhere till maybe the quarter-finals.
Castle: Now to see how much of the old they can keep while still moving forward. Also, bets on the season finale offing the FBI partner (that or she's part of some super uber conspiracy).
Edit: Agents of Serenity: Episode 2. The team building episode. The show still feels like Firefly: Marvel Edition, and it's beginning to feel like the reason to watch the show are for the movie character cameos rather than for the show itself.
