"Last Call", Person of Interest season 3 latest episode, was aired on February 25 after three weeks of hiatus. The episode didn’t feature too much action scene or chasing scenes but it definitely got viewers stuck on their television. John Reese (played by Jim Caviezel) and his crew rushed to the aid of a distressed 911 operator named Susan Nicholson, played by guest-star Melissa Sagemiller. The call was traced in a call center after a number of a woman named Sandra comes up on Harold Finch’s (Michael Emerson) data base.

While the fast-paced recent episode was very entertaining, it left so much for the viewers to ponder. Are they setting up a new big bad villain? The scenes mostly evolved around an unidentified voice who kidnapped a boy named Aaron to threaten Sandra to erase certain 911 call logs.

The Voice then called Susan and then insisted his demand of having the logs deleted. It was then revealed that the man behind the phone wants to erase records that have something to do with the attempted murder of Tara Cooke who has been flirting with his boss. Mr. Voice is believed to be hired by Tara's wife's boss to get rid of the 911 evidence because she and her boss had an affair. “Tara's boss killed her and made it look like a mugging gone bad.”

The voice was never seen throughout the episode. However, what’s more interesting is the fact that he didn’t perform the job by himself. He hired a group of military-trained goons with connections to a large syndicate to kidnap Aaron which they will use as an accessory to intimidate Sandra who was traumatized when she was still young. She accidentally let a boy she was babysitting drown and up to this day, she hasn’t moved on from it.

"I'm a man of my word,” the voice said after telling Sandra that he will cut the boy to pieces if she doesn’t erase the call logs. Sandra was defiant and the Voice showed that he’s in authority by blowing up a parking garage.

"Call it a warning shot. Aaron is still alive... for the moment."

Mr. Voice definitely is that episode’s biggest take away. Why is he so powerful? Who is he? Will he appear in the show more often? Is he the newest biggest villain in town?
