Jersey Shore

The gang gets ready to say good-bye to Italy and head back to Seaside Heights in the Season 4 finale, but tensions between Mike and the rest of the roommates leave him doubtful that he'll be joining them back at the Jersey Shore.

After The Situation's prank on Snooki backfires, the guys visit Vinny's family in Sicily and the girls class it up on a Tuscan wine tour. Snooki learns the truth from Vinny about their hook-up, and now she has to come clean to Jionni.

Snooki is devastated over herfight with Jionni, and decides to take a break from the relationship. Mike thinks it's finally his chance to win her over, but it's someone else who ends up comforting her. Meanwhile, Deena has a pregnancy scare.

Snooki and Deena are released from the police station after their accident. Later, Snooki's boyfriend Jionni visits, but their romantic reunion comes to a halt, and a sobbing Snooki ends the night alone on the streets of Florence.

When the roommates take a trip to the Italian Shore, Snooki and Deena party so hard they wind up in bed together. And when everyone returns to Florence, Team Meatball has a run-in with the Italian police -- literally.

Pauly D and Vinny put on a "Guido-themed" comedy show, while Ronnie and Sammi work once again to patch things up. Snooki becomes so distraught over her rollercoaster long-distance relationship that JWOWW and Sammi decide to intervene.

The boys harass Deena for stealing a girl from Vinny's bed, leading her to anxiety and self-doubt about her relationship with the roommates. Ronnie and Sammi are back to their old ways, but this time The Situation is involved in their drama.

Deena and Pauly D consider the consequences should they smush, while The Situation tries to take his friendship with Snooki to the next level. At the club, Ronnie and Sammi try to be friends but prove that old habits--both good and bad--die hard.

The housemates pack up their hair extensions and Shore Store T-shirts and jet off to Italy for a European adventure -- but the culture shock that awaits them is nothing compared to their shocking new hook-ups.

Vinny and Pauly D take a road trip to Staten Island. Roger becomes more than just a rebound for JWOWW. The Situation reveals Sammi's shady ways, causing Ronnie to question his love for her.

Sammi's return to the shore house puts Ronnie at a loss for words. Snooki's feelings for Vinny persist. The Situation gets with a girl who he's convinced smells similar to cheese, but doesn't recognize he's been pranked in a major way.

Snooki's summer of hookups comes back to trouble her. The Situation pulls a huge prank on Deena and Snooki. But the other guys have the final laugh when they ditch The Situation for taking his time getting ready for dinner.

With the girls upset that Ronnie's temper forced Sammi to flee the house, Ronnie feels alienated. The guys try to cheer him up, and The Situation makes a play for Pauley D's ex.

Ronnie and JWOWW are friends again, leading to Sammi punching Ronnie in the face. Vinny picks up a girl with an over-protective family. The Situation learns Deena's dirty little secret at the barber shop.

The altercation between Sammi and JWOWW causes tension in the house. Ronnie and Sammi keep isolating themselves, missing the first Sunday family dinner. When Ronnie decides to chill and have fun with the rest of the house, Sammi feels neglected.

Pauly D and Vinny go out with their girls one last time. Sammi and Ronnie have a fight during the last night in Miami. JWOWW stirs things up between Pauly D and Mike, culminating in a tense final night.

Everyone is angry with The Situation for being off his game. He gets the roommates kicked out of the club, gets the car towed, practically burns down the house, and proves to be a failure as a wingman for Pauly twice!

Vinny decides between two sets of girls. Meanwhile, now that Angelina is gone, Snooki thinks it's time that she and J-WOWW bury the hatchet with Sammi. But Snooki's happiness is short-lived as Mike becomes increasingly hostile with her.
