Did we get a new title card? I noticed it last night:

A bit different from this one, which has been in all the season 2 episodes so far:

ashley: I was wondering that myself! (LOVE your new avi, btw!)

nalissa: Yes, Gina is on FF. She is the wife of the FBI agent in charge. I just caught up all the episodes last week and was all sorts of excited when she popped up!

And I am definitely looking forward to V with Morena. The Firefly cast does seem to doing pretty well right now! Would love to see Alan somewhere, too.

A new comment for Ep. 6:
I really like the way Alexis' story mirrored the case story instead of the other way around. The circumstances of the case allowed Castle to deal with her situation better instead of Alexis helping him solve the crime. Neat twist there by Terri Miller. Way to mix it up. :D

This episode was awesome , I keep forgetting lines  and stuff (I have to go rewatch the episode) but anyway my favorite parts were all the Castle/Alexis scenes when Beckett took care of Fagan and told Castle something like "He didnt even cause trouble when I tried to put him to sleep." that was such an awww moment I really liked the part after Castle and Beckett were talking and Espesito and Ryan came and one of them said "Were we interrupting something?" Beckett:"Yes" Castle:"No"  The vampire store reminded me of Hot Topic (a store in the mall has like goth/rock band type stuff).  

Castle —- You're right! It was so the perfume ad!

My favorite moments:

1.) "You smell like cherries" and everything that followed in that scene

2.) Beckett taking care of the baby egg

3.) Castle offering to stay with Beckett while she called the victim's family

4.) Beckett pulling Castle back by his jacket before they entered that building

5.) Castle's evil laugh while carving the pumpkin and then he got choked, LOL

Well, heh. Look at that. Shiny.

Does anybody know where I can get screen caps for this episode?

I concur with most everything everyone else has said.  I'm not sure this was my favorite episode, because I really liked last week's episode too, but this week's at least tied for my favorite.  I think the writer's are really hitting their stride with the right mix of "romance" for Caskett and the right mix of "awkward moments" to keep them both a little at bay. 

I am also loving the extra nuances where Beckett is becoming involved every so slowly with Castle's "other life"–ie. taking care of the egg, asking about Alexis.  From the episode previews, seems like Beckett will be getting more involved in something with Alexis…and I like that aspect very much.  This puts Beckett IN Castle's space instead of Castle always being in Beckett's space.  That bodes well for their "future" together in a romantic sense.

I think the writers are handling the whole "romance" aspect just right.  While it may be moving forward at a snail's pace, it is still moving forward.  And apparently their "chemistry" has become apparent to Ryan and Esposito…nice use of those two to solidify an awkward moment. 

All in all a great episode.  I am so glad we're getting 22 episodes this season.

Am I the only one who never fathomed Kate Beckett smelling like cherries of all things? I imagine some sultry scent. lol
Overall, I loved this episode. I was a bit disappointed with Kate's Halloween costume after all of the anticipation. Slutty nurse (or Nikki Heat!) wouldn't have been realistic for the character, which is fine, but all of that play up and then that just didn't do it for me.
I wanted to slap Castle for the story he told her. I really hope that it was based in truth and she'll uncover that later on. If not, given Kate's history, that move was kind of over the top douchey in my book!
One moment I really liked was when they were going in to arrest the "real" vampire and Castle was going up the steps first and she grabbed his jacket and pulled him back.
Stana is totally my girl crush after this show. I am totally straight, but she is gorgeous and she brings so much to Kate Beckett. Her expressions are just priceless.

Thank God he told us what it was! It was driving me crazy!
