TV viewers should brace themselves for an emotionally gripping season of NBC's "Parenthood."

Actress Monica Potter, who plays Kristina on the popular sitcom, warned that Thursday's all-new episode will be a real tear jerker.

"I have a scene with Zeek that was really, really poignant. I go over to his house and talk with him about being sick, feeling sick," the actress told E! News. She added that she found it difficult to keep her emotions together during the scene.

In a recent interview with The Hollywood Reporter, show creator Jason Katims dropped several spoilers about the final season. 

When asked if someone from the Braverman family will die, Katims said, "The season is dealing with the potential loss of someone, I wouldn't say we're saying goodbye to somebody."

He went on to explain that "They're dealing with mortality. While we've touched on it in season four with Kristina (Monica Potter), we're dealing with it in a very different way in a way. This is something that affects the entire family and it informs what everybody will go through the whole season. Even the storylines that don't seem like they're going to be connected to that story, they're still affected by it. It's something that definitely influences the whole season. Tonally, the show will have pockets of humor and lighter moments throughout but overall the season will have a lot of gravitas because of the subject matter."

The executive producer also promised that the final scene of the series will give be "very emotional," but it will give fans closure. It "also gives a window into the future of all the characters on the show," he said.

"The season takes place over a time span that is a little bit longer than the actual amount of time that 13 episodes takes. It's closer to a year than three or four months. There's one time jump that we have that happens around the middle of the season where we jump forward a few months. In the final episode, we might take some liberties though, in order to give a window into where our characters are headed," he said.

Katims also hinted that there will be a change in the dynamic of Joel and Julia's rocky marriage in Season 6. Fans will see Joel "trying to get back into Julia's good graces. It's about refining Julia, who decides to move on with her life," he said in am interview with TVLine, 

Season 6 Episode 2 of "Parenthood" airs on Thursday, Oct. 2, on NBC.
