“You say things that aren’t true and you always don’t allow me to speak!” Howell tells Chastain, who is joined by first stew Brianna Adekeye during the sit-down.

“You’re being rude,” Chastain says. “You’re acting like a 3-year-old. Why don’t you go live on your glass house on land, because you’re clearly not a yachty.”

Chastain and Howell will continue to battle it out on the Below Deck season 5 reunion, which airs Dec. 12 at 11 p.m. ET on Bravo.

They’ll be joined by fellow crewmates Nico Scholly, Brianna Adekeye, Matt Burns, Bruno Duarte, Jennifer Howell, Baker Manning, Kyle Dixon, Emil “EJ” Jansen and Captain Lee Rosbach — who will spill on the secrets of the season in the Watch What Happens Live special (deckhand Chris Brown, who was fired earlier in the season, will not appear).

Of course, there’s plenty of drama to get through, including Scholly’s showmance with Adekeye, which appears to go up in flames on Tuesday’s finale. He’ll be in the hot seat, too, as he weighs in on his feud with bosun Jensen, who nearly had a showmance of his own with Manning.

As viewers get to the bottom of what Jensen and Manning wish they did when they had the chance, they’ll also learn more about Burns’ season-long struggles to get his kitchen in shape, Duarte’s tensions with the interior crew, and Dixon’s arguments with Chastain. Rosbach will be there, as always, to offer his no-nonsense take on all the conflict.
