In the "Keeping Up with the Kardashians" Season 10 finale "The Last Straw" that airs on Sunday, Kourtney Kardashian attempts to keep her emotions in check and her family stable as Scott Disick's behavior spins out of control.

Khloé Kardashian decides to meet with Caitlyn Jenner and salvage their relationship.

Kris Jenner finally gives Corey Gamble boyfriend status.

Kourtney talks about Scott with Kris and Kim and says her emotions are all over the place. She tells them Scott's friend is worried he'll end up in jail, and Kris says that may be the best thing for him since he'd be away from his demons. Kim says Kourtney has done everything she can to help Scott.

In the trailer for the season finale, Kourtney talks to Kim about Disick's behavior.

"As time goes on, Scott seems to just get worse and I want to be mad, but I also just worry about Scott's safety and, you know, he definitely has a problem that he has to deal with. So, it's hard. I feel like my emotions get all over the place," Kourtney explains.

Kris tells Kourtney in the clip that going to jail could be the best thing for Disick since rehab has not worked.

"That's the biggest wakeup call of all to be thrown in jail with no alcohol, no nothing. No pillow --"

"No one to bail him out," Kim interjects.

In a narrative later in the clip, Kim explains that Kourtney now sees things about Disick that she was unaware of before.

"I think she has done everything she can to help Scott, and that's just what's really heartbreaking," Kim says.

Watch the "Keeping Up with the Kardashians" Season 10 finale on Sunday, Oct. 11, at 9 p.m. ET on E!
