Yes, they are so good, I've combined them into one delicious block of awesomeness.
Castle: What an episode! Tying the murder to Beckett's mom's killer came pretty much out of nowhere (well, except for last week's preview), and it made an average case much better. Not a lot of detection going on, although the Johnny Vong running gag was funny. It was the last few minutes of the episode that really sold it. The realization of the real killer, Castle putting his own money up to help catch the killer, Castle taken hostage, Castle's headbutt-fu, Beckett performing CPR on the killer at the end...great moments all, and the little coda with Castle and Beckett added a little more to their relationship without it going into "I love you, smoochy time!" territory. Plus, now we have the "who got Beckett's mom whacked?" question to carry us through the rest of the season.
Leverage: Awesome awesome awesome episode. Backstory on Nate, two cons in an hour and a half's time, hot redhead client...all the bases covered, and then some. Plus, instead of a shoehorned in Sophie appearance (seriously, I love Gina Bellman, but I'm ready for her to be back full time), we get Nate drinking again. Lot of stuff to take in, and only a few more episodes of Season 2.5 to do it in. Loved the reveal at the end, loved the loan shark's bastardization of the Leverage motto, loved the hiding places for the "emergency fund", loved the fat guard who ran away from Elliot. This is the episode to show people when they ask "is this show any good?". Because, yes it is good.
Scrubs and Better Off Ted: Both pretty darn good this week, with Scrubs finding a good groove with its med students, and Turk and Cox becoming a great duo. BOT, meanwhile, had a bagel tossing game and the very unsettling scenes of two people having sex via a translator programmed with Phil's voice. Really funny scene though, and worth watching for that alone. Actually, that was about the bulk of the episode, but it doesn't matter, it paid off and thus was worth it. Thursday comedies up next, and that'll be the week.
