'Person Of Interest' Season 4 Spoilers: Will Jim Caviezel, Michael Emerson Meet "YHWH?"

The Season 4 finale of Person of Interest is upon us on CBS. In Episode 22, as the war for supremacy between two Artificial Intelligences escalates, will Finch (Michael Emerson) and Reese (Jim Caviezel) meet the winner of the battle, who will call itself the deity known as, "YHWH?"

As we previously mentioned, the fourth season started with Team Machine on the run. With new identities, the group had to lay low or else they would be detected by Samaritan's radar. But all things changed, when Shaw (Sarah Shahi) was taken prisoner by the mysterious Greer (John Nolan). Samaritan is determined take over humanity and destroy the Machine.

In our recent recap, Team Machine found themselves in two different wars. Reese and Elias (Enrico Colantoni) were both captured by rival, Dominic (Winston Duke). While Shaw was being taken to a different location, Root (Amy Acker) and Finch found themselves trapped in Samaritan's base. In order to save them, the Machine gave up its location to Greer.

According to TV Guide, Finch and Root are trying to get to the Machine's location before Samaritan's operatives arrive. Still in bad shape from his gunshot wound and being left out in the cold, Reese continues to navigate the battle between rival gang bosses, Elias and Dominic, who have both lost their right-hand mans.

With the group receive help from Control (Camryn Manheim), who has already discovered Samaritan's "correction" plan? Because this is the season finale, get ready for a shocking cliffhanger and a pretty big body count.

Showrunner/creator Jonathan Nolan teases to the site, "The finale features the potential death of up to three major characters."

Could The Machine be one of those deaths?
