Season 5 of the CBS series "Person of Interest" will see Root (Amy Acker) and Harold Finch (Michael Emerson) working together to recreate an all-new, better-than-ever Machine.

According to The Hollywood Reporter, the team will rally and go on the offensive against the Samaritan. To help their cause is the Machine, their "key" to salvation and perhaps the only means to bounce back from the grim ending in the season 4 finale. Root and Finch will reportedly make sure that the Machine, which was last seen on the "brink of death," will serve its purpose. While the two seem to intent on repairs and restoration, they still will not be able to see eye-to-eye. As Finch does some tweaks on the mechanism, he will find Root just a foot away, breathing down his neck the whole time.

"It's an interesting kind of grudging camaraderie that they have. People that keep saving your life and stuff, you tend to warm to them. The question will be, can she prevail on him if they do indeed collaborate on the rebooting of the Machine. What [aspects] of her character will the Machine end up with?" Emerson said in his interview.

The actor said that his character might also change course, as he starts considering suggestions from Root. He shared that Finch could give the Machine more freedom, something that Root has been demanding for a long time. Once he opens up for the new possibilities on what they could do to make it stronger, Finch would be surprised that the Machine could be an even "greater warrior" than ever before.

Meanwhile, fans of the sci-fi crime drama will be sad to know that season 5 will mark the end of their favorite series. Executive producer J.J. Abrams shared with TV Line his thoughts and said it was a wrench because the writers have so much material to work with.

"My guess is [Season 5] is the final season. The only heartbreak there is how much good story there was to come if it were to have continued," he said.
