After last weeks excellent episode, this installment was, frankly, a disappointment.

FBI agent Kat Russo (Katheryn Winnick) asks Sheriff Nick Monohan (Frank Grillo) to assist her in apprehending a suspect who lives in The Gates. Once they search his house, Monohan realizes that the suspect has incriminating evidence on members of the vampire community, including Dylan and Claire Radcliff (Luke Mably, Rhona Mitra.)

Nick goes to Dylan, who arranges a meeting with some of the vampire leaders. He must figure out a way to protect their secrets without incriminating himself. Many of the secrets of the vampire community, including former identities, are on a flash drive in a safety deposit box, and Kat is trying to get a warrant to get the box open. Nick is given a dummy flash drive, and his job is to switch it with the real one.

Nick makes the switch, but gets caught in the act. He is still able to pass off the fake flash drive as the real one, and Kat mysteriously decides not to press charges. Finally, Nick gets suspicious and does some digging, only to find out that agent Russo has been dead for two years. Her suspect is the man who made her into a vampire two years ago, and she has come to kill him, as well as every vampire he knows.

Elsewhere in The Gates, Andie Bates (Skyler Samuels) finds out that she can kiss Brett Creszski (Colton Haynes) and his werewolf powers will allow him to heal quickly. However, she realizes she would rather kiss Charlie Monohan (Travis Caldwell). Her friend Mia Mueller (Devyn Tyler) gives her some Devils Weed that she stole from Devon (Chandra West), and it seems to do the trick. However, when she goes to see Charlie, she catches him kissing Lexie Wade (Rachel DiPillo), one of the werewolf clan.

Finally, the Radcliffs get a shock when they discover their daughter Emily (Georgia Cole) is missing.

What Worked

Sheriff Nick continues trying to protect the secrets of his constituents while still upholding the law. This always makes for great tension, and is one of the best things about this series.

The shocking ending, when Emily is missing, and her parents realize who the culprit is, made it all worth it. It also practically guarantees that the next episode in two weeks will be a big improvement.

What Didnt Work

The idea that Kat Russo could come in and conduct an entire investigation, including getting several search warrants, without somebody figuring out she was no longer an FBI agent, strains credulity. In fact, how is it possible that the vampire community didnt even know she was now one of them?

Plus, all of the vampire secrets are on a flash drive in a safety deposit box? Really? That seems a bit convenient.

The whole idea that Nick would risk his career to tamper with evidence in an FBI investigation like this is ludicrous. The only motivation provided in the script was that the vampires threatened to kill the FBI agent if he didnt.

Does Dylan hate Claire, or does he still love her? Wish hed make up his mind!

It briefly looked like we were going to get some more insight into the mystery behind officer Leigh Turner (Janina Gavankar), but the writers were teasing us.
