Castle “Linchpin” Review

Castle Linchpin Season 4 Episode 16

This episode of Castle, called “Linchpin,” was about finding a little girl who just so happened to be the linchpin to a plan to start World War III. Killing her is that little event that’s supposed to trigger the bigger event, and boy what a bigger event that is. With a lot of twists and turns along the way, it turns out that the mole in the CIA, the one trying to start the next world war, is none other than Sophia herself.

But before Sophia earns herself a bullet to the head, she does have a very interesting conversation with Kate. Sophia tells Kate that she and Castle also had a lot of tension and attraction. That they gave into it finally, but afterwards all they had left were all those things that drove them crazy about each other. Sophia reveals that she wishes she never slept with Rick and even though we know that the woman wasn’t exactly known for telling the truth, I have to think she was serious about that. I don’t necessarily think that the same thing would happen with Kate and Rick, but I am thinking that Kate is definitely going to be taking those words to heart.

After all the mystery and drama involving the CIA and former KGB agents though, one of the most intriguing plot points came at the end of the episode when Sophia revealed that Castle’s father may have been in the CIA. Again, I’m inclined to believe she was telling the truth at that moment and I for one cannot wait to see where that storyline goes. So far Castle’s family life has been pretty tame and I’m very much in love with the idea that there could be some fantastic skeletons hiding in his closet.

My favorite bits..

Beckett calling out and reaching out for Castle as the car sank further and further down.

“That whole sinking car thing, much cooler in movies than it is in real life.”

“I was Special Forces, I used to eat ‘classified’ for breakfast and yet writer boy can know??”

Castle admitting that he did in fact sleep with Sophia.

Beckett asking how big the “club” was. Ooh, ouch.

“There is no ‘big deal’, sleep with whoever you want. The more, the merrier!” – You know, the more she protests it’s no big deal, the more we all know that is a big deal.

Ryan giving Beckett a double-take when she asked to borrow his car. Who can blame him?

Gage coming in to save Beckett and Castle just in the nick of time. Oh boy!

“I have no idea what they are talking about, but this is exciting.” – Castle took the words right out of my mouth.

Castle’s little smile after Sophia gave him a thank you kiss for figuring out how to narrow down the search for the girl.

Beckett’s look when Sophia said she wished she and Castle had never slept together.

AHA! I KNEW IT! I totally had a gut feeling that Sophia was either working with the mole, or was the mole herself.

Oooh….but I didn’t think she wasn’t an American. Nice one.

Wait. What? Castle’s father is CIA??

Esposito’s shock when he found out that Ryan knew what was going on.

Castle telling Beckett why he became interested in her as a Muse.

Beckett leaning over to bump arms with Castle as they walked away. Aw.
