Castle "Disciple" Episode Review

*Review contains spoilers, so read at your own risk!*

Guess who's back in this thrilling, yet creepy new episode of Castle? Yep, the 3XK killer! Haven't heard from him in a while, have we?

He returns in a very creepy manner, too. Killing look-a-likes of the FBI branch. He first starts off with Lanie and then goes to Esposito. Wonder who he will target next? And is this a sign that he's gonna go after the real versions of themselves or is this just a creepy way of him saying "I'm back"? 

Either way, it's creepy. It especially freaks out Lanie the most. I don't blame her one bit. She tries to figure out first who could have been after her because at first, they don't think of the 3XK killer. We then find out that while she was partying with some friends, somebody drugged her drink and she couldn't remember anything from that night. Which is probably when the guy came after her.

The therapist ended up being in on it as well. We aren't sure how far into the case she was because by the time the team figured it out, she had disappeared. 

That flash drive was creepy, wasn't it? What an odd song. Though Castle was right and the 3XK killer is truly back. I wonder what the killer's move will be next?
