'The Enemy Within' Episode 2

The follow-up to last week's strong premiere starts with a sluggish subway robbery. The bad guy takes the laptop and password of Dean, the good guy. Dean was a former CIA agent who also was a former operative of Shepherd's. Despite getting sent back to prison, Shepherd is going to be a big part of the FBI's process, especially with Agent Will Keaton running the show. He knows how valuable an asset she can be.

Right away, Keaton's team felt hesitant when he mentioned bringing Shepherd back into the fold. I'm hoping there are some tense moments with Shepherd and his supporting cast. This Kate girl seems like a prime candidate. At one point, Kate is trying to track down video surveillance of the subway robbery, but Shepherd lectures her on why that's a waste of time and why she needs to start thinking differently. Kate took it in stride, but I don't foresee her always doing that. I hope not, anyway. The other guy on Keaton's team is pretty boring and forgettable so far. At least Keaton isn't weak around Shepherd. When Shepherd demands to see her daughter in exchange for her help, Keaton calmly says, "I'll think about it." He doesn't seem manipulable.

Anna is the mole we know about after seeing the final scene in the premiere episode. It's fun watching a mole when you know who it is. It's like watching a magician from behind the scenes. All of a sudden, you see exactly how the tricks work.

We got a new technological term, which I'm hoping becomes a weekly tradition: Meshes, which are basically underground, smaller networks of service connections. Instead of using giant, easy-to-trace phone towers, Tal and his bad-guy crew know how to make themselves harder to find. Shepherd, of course, knew exactly how Tal would use these underground grids, probably because she has used them before herself (heck, maybe she's still using them!)

Keaton and his partner found one of the guys from the subway robbery in an abandoned building. They had a shootout that led to a horrible fall from way up high, which resulted in the bad guy's death. But the more interesting moment occurred when Shepherd not only grabbed Keaton by the very cuffs restraining her to get him out of the guy's line of fire, but also stayed put as Keaton asked her to. Yeah, he was willing to take Shepherd to see her daughter after that.

Keaton and Shepherd had some sweet character-building moments. We got a touching flashback of the last time Keaton saw his wife. We got to see Shepherd have her long-awaited visit with her daughter, Hannah; it was cute and subtly realistic how nervous they both got right before the interrogation door where Shepherd was being held opened.

The episode ended with a rather dull shootout that was worsened with poor camerawork. But the FBI secured a woman who worked closely with Dean, and she revealed why Dean might've been a target of Tal's on the subway. Dean was researching a mountain range in Cuba. Looks like that'll be the focus of episodes to come.

All in all, just an okay episode. There weren't a whole lot of threads picked up from last week, but the character arcs gained more dimension, and the groundwork was (possibly) laid for the next several weeks. The action wasn't all that great, either. We did get a fun moment for Anna, Tal's mole. She checks in on one of the guys the FBI caught while he's detained. He knows she's a mole, which she uses to her advantage. She sneaks up on him and chokes him to death. Guess Tal didn't want his weakest links left behind, and he's got a mole to do his dirty work for him.

Shepherd ended the episode by telling Keaton not to trust anyone, because of course everyone has the potential to be a mole. I have a feeling the reveal of who Tal actually is will be the big twist. Maybe Keaton isn't the nice guy we all think he is. Maybe there is no Tal. Maybe Shepherd is playing both sides still. So many possibilities.
