This was one of those Person of Interest episodes that was fair for most of the hour, but really became interesting towards the close.

I certainly appreciated that Finch got some time to shine and really show off his computer skills again. Seeing him take part in the so-called espionage of the work, rather than just the guiding voice on an ear piece, is always a good change up.

It made perfect sense that the tech guy was involved to investigate a high level tech executive. This is where Finch does his best work.

And while I liked the aspect that Finch had someone to talk to about all the technical computer stuff (loved Reese asking if they wanted alone time), a lot of it felt like we were watching Finch work on a computer and spout out stuff that's a little more complex than I, or even Reese, would normally understand.

That's certainly fine because that's what his character does, but after a while, it felt a little tedious. Yet, it was finally cracking the mystery behind the tech company that perked my interests back up.

China was behind it all?!?

Even more so was the company head happened to be the real traitor by selling information to them.

But it turned out that China was more of a decoy than the real backer. That super secret and dangerous group that was working Kara Stanton happened to be involved here as well.

It was a shocking turn having the boss turn the gun on himself, but these are clearly powerful people. So powerful, in fact, that they want to infect the machine and much more.

Why? Who knows, but this form of secretive enemy is going to be very hard for Finch and Reese to beat.

On top of it all, the guy who I thought was in charge, turns out to be just another person working for someone higher on the food chain. Just what is their ultimate plan?

In a lot of ways, "Trojan Horse" was all about uncovering some secret truth and the larger players pulling the strings for all the parties involved.

Cal Beecher, who we've never really been too sure of as a good guy or bad guy, revealed his true colors of not being connected to HR. The only problem was his digging around with Elias (who I was glad to see still plays Finch in chess from time to time) forced his godfather, the head of HR, to call a hit on him.

I really wish we had some more time to get to know Cal, but he definitely went out a good guy. It was a pretty dramatic moment having Finch have the phone call, Carter learn he was in Washington Heights and Fusco reveal officer down.

Of course, the music enhanced the emotional aspect of it (something this show does very well), and now Cal Beecher is no more. Hopefully, Carter gets some revenge for him.

Similarly, I loved Sarah Shahi's return as Shaw. She wasn't really prominent to the story at hand, but she was around just enough to continue her arc as well as begin her search for Root.

It was even pretty funny that Bear didn't attack Shaw when she infiltrated Finch's base. More so, Bear continued to prove his effectiveness and just be so darn likable with each attack, bark, or settling into a comfy seat.

But I really enjoy how everything finds a way to connect itself and keep things ongoing rather than close it all up each episode. The continuing stories, whether I enjoy one more than the other (this new group is far more interesting than HR), really helps create the world of Person of Interest making it feel very open, large and all encompassing, even if it's a small amount of characters trying to save it.

I do have to admit I'm a bit disappointed that after a three week wait, we'll have to wait another three weeks for the remaining episodes of the season. Not sure why we just couldn't get the final ones in a row, but at least "Trojan Horse" seemed to be the set up for what we can expect as Person of Interest Season 2 draws to a close. I'll be excitedly waiting to see Reese, Finch, Carter, Fusco, Bear and maybe even Shaw finish it all out with a bang.
