This episode is MESSY

Kristen has managed to facilite a meet up between her and Miami girl aka Ann Marie, when Ann Marie just "happens" to be in LA for some unknown reason. Kristen basically convinces Ann Marie to go to SUR while Tom and Ariana are both working and confront him about cheating on Ariana. Ann Marie agrees, but when she gets to SUR, not all goes as planned. Tom and Ariana dip out (if you're caught up through season 11 you'll appreciate that reference) and they leave SUR completely. They straight up get in an Uber and drive away. Kristen acts like this was just the outcome she was hoping for, but it's very clear she is not happy that Tom wasn't "caught", nothing was revealed, and it did not cause Tom and Ariana to break up. If anything, it brought them even closer.

After Tom and Ariana leave, Kristen and Ann Marie go out to the front patio to have a drink and when Scheana comes out to ask what happened a shouting match ensues between her and Kristen. This causes the manager Diana to come out to defuse the utter chaos that everyone in the restaurant and the street can now hear. But instead of calming down, Kristen has some choice words for Diana and she's asked to leave the restaurant. 

When Tom and Ariana eventually do come back to finish their shifts, Ann Marie makes another appearance but this time Tom stays and is very clear that he never slept with Ann Marie. Ariana joins in telling Ann Marie that what she is doing is very inapproiate and has her escorted out of SUR. 

No one can really understand how or why Ariana can believe Tom so easily knowing his past. But we know why. And we spill the beans, or should we say we spill Arianas beans, during this episode. If you want to know her little secret, listen to the episode right now!
