After watching "No. 13 Baby," all I could think about was a cat and mouse chase. The hour felt like a non-stop, circular chase, but instead of the cat chasing the mice, for the most part, it was the other way around.

Henry's the cat and he's after one mouse, Jessica Matthews. And he has all these other mice chasing after him in the hopes that they can finally take down the mean, old killer cat. 

To make the situation even more complicated on Covert Affairs Season 4 Episode 13, there was even some mouse after mouse action going on. Okay, I've probably overplayed the cat and mouse theme just a tad, but that's the best way I can explain what's happening on the show. 

I never expected to say this, but I'm getting a little irritated with this Chasing Henry storyline. He's a bad guy, who has done terrible things. He's supported terrorist organizations, blown up a helicopter of people, set David up to take the fall for it, plus been involved in plenty of other nefarious activities.. Those are horrible, horrible acts, but why? What is his end game?

At first, Henry's justification for some of his activities was to set up Arthur and make him pay for Jai's death. Which never really make any sense, since we know and Henry has to know that Arthur wasn't culpable for Jai's death. But, whatever, he's pissed about that.

When he found out Teo's son was involved with a terrorist group he was already funding, he used the connection to his advantage.Teo died and now Arthur is facing trial for helping his "terrorist" son. That was just a small portion of Henry's overall plan.

The best I can decipher at this point is that Henry's been creating threats that he doesn't believe the CIA can solve and then he wants to swoop in and make it right. Basically, he creates the fire, puts it out, and then gains more power within the intelligence arena. In addition, he has rogue allies on his payroll.

With Annie back in Washington, D.C., the story about Sana and her husband, David, was just dropped. I hope that's not the last we hear about them, because they are caught up in this web of deceit and destruction. For now, the investigation shifted to analyzing the laptop  Annie got in Geneva and tracking the money.

With the help of Calder and Auggie, they were able to make significant progress against Henry, but it didn't come without a cost. In many ways, Annie became a reflection of Helen, though she went about going dark in a different way. Auggie knew that Annie was alive and going off the grid.

Since he had that information, it made Auggie's actions disappointing. He betrayed Annie and not just by sleeping with Helen. Though, that's certainly a part of it. Auggie knew he was going to be out of contact with her. He never should have had Helen following Annie. It was reckless. And, it may have been why Helen was killed.

It wasn't clear whether Helen was at the bus station because she was following Annie or Henry. When she was confronted by Henry, she didn't do it as "Jessica Matthews," that false connection just came about and she went with it. And, she made an honorable split second decision. She took the heat off Annie by taking the cover identity.

Though, she probably didn't expect Henry to just shoot her right there at the bus station. He was reckless. Instead of getting information out of her, he just took her out of the picture. Helen's death was tragic, but it won't be in vain. Now, Henry will believe he's gotten rid of his problem, so he won't see Annie coming.

Plus, Calder and Auggie's investigation has proved successful. They have the email that shows that Henry was complicit in taking down the helicopter and they found out the name of his money man. Will that be enough to bring down Henry and save Arthur? 

There are only three episodes left in Covert Affairs season 4, which should be just enough time to get the evidence needed to put Henry away behind bars for the rest of his life ... this time. Of course, if he makes it out alive.
