This episode knocked it out of the park. Funny, thrilling, mysterious, and fantastically romantic all topped out with a compelling murder case.
The usual classic banter between ryan and esposito and castle and beckett was there and the hampton's local cop only added to that.
The fact that Castle himself referenced "Caskett" was an awesome nod to the fans of the tv show and the writers are just astounding for doing such fan service.
I'm also glad that ryan decided to keep castle and beckett's relationship a secret from esposito and everyone else. Just goes to show you how awesome of a character Ryan is becoming in this show. Don't worry, esposito is still amazingly awesome as well.
All in all, this episode was sweet on the fans, great as a murder case, and sweet as a romance.
5/5 Absolutely loved everything about it! :D
