In tonight's Vanderpump Rules Season 2, Episode 4 recap, Stassi Schroeder and Jax Taylor fight about his modeling shoot, while Kristen Doute fights with everyone. Let's take a look at tonight's top five craziest moments. 

5. Stassi isn't crazy about Jax's model shoot

Is Jax regretting getting Stassi's name tattooed on his arm yet? We wouldn't be surprised, as she lectures him for taking part in a Kitson modeling shoot with a female model who seemed quite interested in Jax. Jax later comes over to Stassi's place, but she belittles him for his sweater line plans; for his taste in, uh, porn; and for not being able to hang a painting. Don't worry, Jax  we have trouble hanging frames, too.

4. Kristen tries her best to suck up to Lisa

Lisa Vanderpump certainly does not seem pleased that Kristen Doute is returning to SUR after her suspension. Kristen claims to Lisa that she'll be on her best behavior, even though Kristen's nemesis, a Villa Blanca employee named Ariana Madix, is now working at SUR. There are rumors that Tom Sandoval and Ariana have slept together, so you can understand why she and Kristen aren't besties.

3. Tom and Ariana flirt. A lot.

Did Tom and Ariana actually sleep together in the past? Ariana claims they haven't, but Jax suggests otherwise. Even if they haven't, they're certainly getting flirty as Tom trains her at the bar, and they make tons of little jokes. We've never heard the word "clavicle" sound quite so sexy.

2. Stassi fights with Scheana in the alley

Stassi decides to take things into her own hands by asking Scheana whether Ariana really did sleep with Tom. Scheana claims they didn't, but Stassi is skeptical, telling Scheana that Ariana better not be a "cheating whore." Yikes.

1. Kristen and Stassi each call each other a "bitch"

Kristen and Stassi usually seem tight, but tempers flare when they grab drinks with Katie Maloney and Kristina Kelly. First, Kristen accuses Stassi of being too friendly with Scheana. Then, when the girls want Kristen to think about dumping Tom, Kristen explodes at Katie, telling her to "cut the st." Plus, Kristen and Stassi each refer to each other as a "bitch." So much for the ladies making progress.
