"Person of Interest" fans were shocked during Tuesday's (Nov. 19) episode when fan-favorite character Detective Joss Carter (Taraji P. Henson) was shot and killed. No one saw the death coming especially since Carter and John Reese (Jim Caviezel) finally kissed after three years.

The show's creator Jonah Nolan discussed the shocking death and romantic kiss with TV Line saying that killing off Carter was a difficult decision but a necessary one.

"The primary concern is to tell a compelling and entertaining story," he said. "Everything else is secondary. These shows are hard to make, so when you find a great collaborator like Taraji, the last ting you want to do is shake it up."

"But the thing driving us from the beginning is that mandate of 'Keep it f**king entertaining,'" he continued. "You've got to keep things moving."

He also said Henson was fully prepared for the shocking twist but she didn't know when it would happen.

"The promise we made to Taraji and all of our actors is we weren't singing them up for a show where, even if everyone was wildly successful and the ratings were great, we'd have them spin wheels for 200 episodes," he explained.

"This was always going to be Carter's story. She was never meant to last forever. Art imitates life, and sometimes the good guys don't make it," Henson said. "We always knew it was going to happen, so it wasn't a surprise. It was just about when."

Even though Henson wasn't shocked about the death fans definitely were and are still having a hard time accepting that Carter will no longer be on the show.

"I'm still in denial. Is Carter really dead? It was heart wrenching watching that epi & ive been a Joss-John shipper since Season 1," @FearlessAl19 tweeted.

"This can't be then end of Joss Carter, I refuse to believe that. This is not happening," @Hey_Blue3 posted.

There were even some fans who tweeted that they didn't want to watch the show anymore because of Carter's surprise death. Hopefully they will in tune because Nolan also hinted that there is going to be a "messy" fallout from her death. Maybe Reese will seek revenge?

As for that kiss Reese and Carter shared, Nolan said the entire thing wasn't in the script but while shooting the two felt it they needed to go for it.

 "The interesting part about the kiss is that it actually wasn't scripted," he told TV Line. "It was just a swapping scars moment. So when the actors went there, it was all of their own volition, because in that moment they both felt it. And when you removed that element, the scene didn't feel quite the same."

Are you shocked Detective Joss Carter was killed off?
