It's about to become a battle of the Green Team on Top Chef: Boston when the chefs unleash their inner demons as they talk desserts that lead to threats.

In a sneak peek of the next episode that was posted on Carter Matt on Saturday, Keriann, Aaron and Stacy are going over their next dish to serve to firefighters when things go up in flames (no pun intended). They realize that they might end up with only desserts, which according to Stacy, that would leave them "kind of f---ed."

Keriann and Aaron then talk about what they could use for a dessert basket when Keriann mentions that she went to pastry school. She asks Aaron what he thinks, but he informs that he's not a pastry person- she is.

"She straight up said, 'I went to pastry school,'" Aaron said behind the scenes. "And then when I try to hand it over to her and say, 'Hey look, let's follow your lead,' she has nothing to say."

Keriann just wants to be careful about what they serve after Aaron suggests gelatin because she wants to step away from something "molecular."

The two then start to argue about how this is going to work where Aaron even has to take a moment to breathe. Keriann then tells him that he just wants to be an "a---ole," which Aaron says, "Trust me, you'll know when I'm an a---ole."

Top Chef airs on Wednesdays at 10 p.m. ET on Bravo.
