^ Probably. Looks like they at least left things open. It did look like a good opportunity to introduce a new character.
A lot of people think Person of Interest is like a Batman TV show, with Batman/Bruce Wayne split up into Reese and Finch.
And since the show keeps developing more recurring villains, people are calling them the rogues gallery.
Also, Carter is kind of like a pre-commissioner James Gordon and Fusco is like Harvey Bullock.
And Paige Turco's character is Catwoman.
I've been thinking about the Batman analogy lately too. Batman can be split between Reese and Finch, but you can also put Finch in the Alfred role.
