Ozark showrunner Chris Mundy explains why Wendy Byrd checked herself into a mental institution in the show's penultimate episode.

The final episodes continued the show's positive critical reception for its performances, direction, tone, and plot twists.

The last few episodes see the reemergence of Wendy's father (Richard Thomas), who successfully sues for custody of Charlotte and Jonah to take them away from Marty and Wendy.

As a result, Wendy checks herself into a psychiatric facility in the next episode, the same one her brother Ben (Tom Pelphrey) was placed in Ozark season 3.

When asked by TVLine, Mundy says Wendy's decision was simultaneously genuine and a way to manipulate her children into staying in the Ozarks.

He goes on to say that Wendy would have stayed in the hospital if Charlotte and Jonah hadn't come to visit her in the last episode, convincing her to come home.

Though Ozark's finale was polarizing to fans, it has a clear line of cause-and-effect logic from the writers, the basis of all good storytelling.

In the end, there might not be any more Ozark, but the show's consistency with characters like Wendy is just one of the many reasons it's one of TV's best crime dramas.
