Call them Finch's Angels.

Sam Shaw, Joss Carter and Zoe Morgan had their time to shine on Person of Interest this week, as the bevy of beauties donned sexy club attire, excitedly compared weapons and left the boys to play backup. Nothing quite like a ladies night, right?

Using the femme fatale trio as bait on "Lady Killer," the Machine pulled up a number for a Boston playboy who teetered on the lines of stalker/killer and just plain overly attentive.

It was nice to see Warren Kole as the focus, especially since he's played a bad guy on Fox's The Following and a good guy on USA's short-lived Common Law. It wasn't easy to tell which way his character, Ian Murphy, would fall, although the ominous music played tried to convince viewers when he was holding a knife or following Carter.

Except the real truth was about familial lineage and social class. Murphy had a son and was tricked into believing the girl he loved had an abortion, all by the father who wanted an heir and not someone of the "low class."

Which made it fantastic when Reese was able to punch the social elite grandfather and it ultimately ended with a happy day for Murphy. Plus, there's a possibility of a Carter romance further down the line.

And I was glad that Carter was the one chosen out of the three at the club (loved Shaw's look when Murphy passed her by). It was nice to see Carter get a little more involved, reveal that she's still really a detective even if she's officially an officer and love isn't lost on her.

Shaw, on the other hand, while she acts like a bad ass (and is a great shot), does have a soft spot beneath that steely exterior. It just happens to be for the fuzziest of the group, Bear. Nice to see he got a huge bone and spiked collar.

It was good to see that all three women had vastly different personalities while all being strong characters in their own right. Although, it was funny when Reese pointed out that Shaw always looks "angry."

The return of Zoe was such a treat and her rapport with Reese feels so natural. She's never overused (but is that possible?), and she provides her own sexy charm to whatever is happening. Lucky Reese gets to walk her home.

While Finch, Reese and Fusco were more downplayed for the hour, they still had their humorous moments: Fusco hitting on the ladies in the club, Reese discussing his love life with Shaw and Finch telling Carter to dress as least conservative as possible. And even though it was fun to see the women in the limelight, I'm looking forward to watching Reese back at the forefront, getting to show off his combat skills again. Maybe even some more backstory for him as well.

But in classic Person of Interest fashion, the B story of Root in the psych ward weaved throughout the hour was just as important. Not only was the Machine continuing to aid the crazy chick (Amy Acker has that character down. Just the way she laughs, stares or tilts her head makes you not want to mess with her and at the same time can't help but want to watch every minute), but it was also preparing her escape.

Her shootout with the government agent sent to kill her was similar to the preciseness of Reese following the Machine's directions in last season's finale, "God Mode." She may not have killed anyone, but she is super lethal with that weapon. Is that progress?

And unleashing her back on the world? What a great start to another mystery surrounding the Machine. Just what is its end game?

Person of Interest Season 3 is continuing its slow build and rise as the episodes keep getting better, the characters are always charismatically delightful and entertaining, and saving the day like a group of superheroes is fun to watch. The next chapter of this series is just getting started.
