On the episode, Brie wants to get a scooter to ride around town instead of getting a second car, but Nikki isn't thrilled about the idea because she doesn't want her sister to get hurt.
In order to keep Nikki happy, Brie tells her that she won't get the scooter, but then she ends up buying it behind her back.
So when Nikki sees Brie on the scooter, she's "so pissed."
"Am I like honestly seeing this correctly?" Nikki says. "Brie literally just promised me that she would not buy a scooter, like what the hell?"
Take a look at the video to see Nikki's reaction to Brie breaking her promise!
Season 6 of Total Divas premieres this fall.
