The cast heads to Miami in the season 2 opener, and the drama quickly heats up when Angelina crashes the party. Meanwhile, Ronnie and Sammi, find themselves in an awkward situation after their recent break-up.

Sammi tries to figure out what Ronnie really did at the club the night before, but no one is saying. And when Angelina interrupts Pauly's game, we see a whole new side of the usually calm Pauly D.

Angelina swallows her pride and apologizes to the girls. Back at the house, The Situation, Vinny and Pauly D have a close encounter with grenades in the hot tub, while Ronnie continues to creep behind Sammi's back.

The ladies feel guilty about keeping Sammi in the dark about Ronnie's bad behavior, so they decide to write an "anonymous" letter to her, revealing the entire truth.

Sammi finds the "anonymous" letter from the girls and once again decides she's done with Ronnie. Meanwhile, Mike, Vinny and Pauly try to juggle four girls in one night.

The anonymous note causes tension between the girls, culminating in a full-blown cat fight. After spending another night in bed with Vinny, Snooki reveals a not-so-little known fact about her pinkeye-prone cuddle buddy.

The roommates deal with fallout from the girls' fight; Angelina starts dating Jose, a guy from the club; and Jenni and Snooki don homemade HazMat suits to clean up the Smush Room in preparation for Snooki's hook-up.

Word gets out that Vinny and Angelina hooked up, and Mike threatens to let Angelina's new beau in on the secret. Meanwhile, Vinny's family comes to visit, and later, Pauly and Vinny fall for the same girl

Things go south for Angelina when the house learns she slept with Jose after smushing Vinny. Then she gets too close to a guy Snooki hooked up with. But it's the last straw when The Situation discovers more unpleasantness in the bathroom.

The Situation reunites with his Canadian hottie, providing entertainment for the whole house. And Angelina tells her roommates how she really feels about them, sending Snooki into a frenzy and finally pushing things over the edge.

Snooki and J-Woww decide to make amends with Sam; Vinny pursues two groups of girls; Mike's antics annoy Snooki.

Mike gets on everyone's last nerve after his obnoxious antics get them all kicked out of a club. Even Pauly is frustrated after Mike proves twice that he's a failure as a wingman.

The roommates say goodbye to Miami and head home in the Season 2 finale.
