I loved the episode as well.  Glad to have the intro to Castle again… gives me hope that new viewers will be able to understand the back story of why Castle is helping, etc….and continue to stay and watch week after week.

Wish there was more Beckett/Castle romantic scnenes but I think there were a few – Have to re-watch….

More importantly, I think I had the biggest grin on my face when the promo for next week's episode came on and some guy asks if Beckett and Castle are together and (i think) Castle says "Not Yet" while Beckett says "No".  Reminds me of the "cherries" scene from last week!!

Just my 2 cents!! Will definitely re-watch!!

Really good. Found myself saying, "wow, this is a good one" about halfway through. Figured out who the perp was abt 10 minutes before the reveal, but the motive really surprised me. I liked how Alexis was so helpful, and that she was mature enough to realize what had happened without Castle having to explain.

I was convinced Sky was going to kill herself (that moment before they find her going thru withdrawls), but was pleasantly surprised that she didn't.

Castle had some *great* lines tonight!

"She hated Obama!"

It was really awesome to see how angry Castle got at the husband! He was furious over Hayley's death, cause he knew this guy was a slimeball as well as what he did to her. Beckett too, she got really angry for a sec when they were questioning the guitarist. Very nice to see these emotions come out. I wasn't expecting it, so I hope they keep it up. Both actors express their emotions very well.

I wonder how much Apple's product placement (the iPods) had to do with the Castle soundtrack being available on iTunes? Interesting. Then again, I absolutely adore Apple so I'm not complaining. They're high-end music players that nearly everyone has (especially celebrities), so it made sense that Hayley Blue had one.

I noticed that Beckett seemed to know a lot about rehab, talking about Hayley's "exit interview" before she left rehab and how Sky wouldn't stop using until she wanted to. I wonder if this had anything to do with her father's alcoholism? Did he go to rehab too? Hopefully we'll find out more about this as the episodes come along. I'd hate to see Beckett's backstory put on the back burner until the end of the season, but I guess it's better than nothing. More interesting, anyway.

A big FTB to all involved in tonight's ep. Definitely one of the top eps so far.

This episode was good but there was one thing that bothered me. In September Richard Castle talked about getting the Beatles Rockband. Yet in this episode Nathan was playing with Guitar Hero.
