The last two eps -- the cliffhanger w/Dana Delaney -- were amazing. LOVED them. Delaney should be a regular, with her Fbbie character dropping in periodically. She was much better served on Castle than she has been on Desperate Housewives, where she hasn't had anything much to do at all since breaking up w/Mike DelFino.
I love that show and I am so pissed that I can't stay up late enough to watch it (and still function at work the next day). I am going to have to get the DVDs of each season. The promo I saw last night with them and the pool table cracked me up!
