WARNING: This article contains some spoilers for the penultimate episode of Snowfall season 4. Read at your own risk.

Snowfall season 4 episode 10 is arriving next week on FX, with the title "Fight or Flight." This particular installment will serve as the season finale of the crime drama, which means it'll bring more intense stories for Franklin Saint (Damson Idris) and the rest of the characters.

Snowfall season 4 episode 10 will focus more on Franklin's family, particularly with his father Alton Williams (Kevin Carroll). Over the past few episodes, he has been contemplating whether he should stay or not. But then, he knows that taking off is the best way for him to ensure his safety.

Teddy McDonald a.k.a. Reed Thompson (Carter Hudson) is not fond of Alton, and there is a possibility that he'll choose to kill him in the event that he stays. In fact, the penultimate episode has seen the former killing journalist Irene Abe (Suzy Nakamura).

In episode 9, titled "Sleeping Dog," Irene was murdered by Teddy after talking about the CIA's role as South Central L.A. cocaine suppliers. The journalist spilled more tea to the public, which prompted him to kill her to stop her from revealing more about his operations.

Teddy is doing everything -- and even willing to kill anyone -- just to keep his operation under wraps. Things get even more intense in Snowfall season 4 episode 10, given that Alton's life is now in danger. It's yet to be seen whether or not he'll make it out alive or he'll be killed in the end.

In addition, the synopsis notes that Teddy is about to make a difficult decision, possibly related to Alton. The promo also hinted at the death of one of the characters, with some speculating it could either be Teddy or Alton as the clip teased an ultimate showdown between the two.

Alton thinks that Teddy is the root of all their family problems, that's why he is determined to take him down. His world will be less dangerous if ever he could get rid of him. The biggest problem, however, is that Teddy is a notorious adversary and he has no problem in killing whoever gets in his way.

Snowfall season 4 episode 10 could likely bring a huge cliffhanger, bringing more stories to explore in the fifth installment. The good news is that there's no need to worry about the future of the series as FX officially renewed season 5 in March 2021.

Snowfall season 4 episode 10 airs on Wednesday, April 21, on FX.
