Plot

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 & Sam are back to their old ways, but this time Mike is involved in their mess.

Welcome back to Italy, where the gang is once again embroiled in much drama. The Situation wakes up and says goodbye to his most recent blonde hookup, whose twin sister is in the bedroom with Vinny -- or was it Deena? "The truth is that Deena and me did tag team a girl," Vinny explains to the camera. "But it wasn't a good tag team." In short, Deena stole the blonde from Vinny in the middle of the night -- and the two ladies hooked up ... before the twin returned to Vinny's bed. Even Snooki is disgusted by the news.

The boys then head to breakfast. The Situation swears that he and Snooki did indeed hook up while she was dating another guy. "The truth hurts," he says with a shrug. Meanwhile, the ladies head to breakfast and Snooki swears that she did NOT hook up with The Situation. Furthermore, she fears that the Situation's claim will ruin her relationship with Jionni. Later, Deena claims she only "made out" with the twin. Hooking up with gals is "fun when you're drunk." Snooki then admits to her own one-time "lesbionic experience." "I licked a nipple once," she says. "It was weird."

Back at the place, the boys tease Deena about spending (half) the night with another woman. They make jokes about the carpet being clean, etc., etc. Deena isn't happy with the treatment -- at all. Later, Snooki calls Jionni to tell him that The Situation is spreading nasty rumors. Jionni is NOT happy -- and demands to know if The Situation's claims are true. She says "no" and Jionni relaxes. The pair make up via telephone. "Let's make babies," Snooki says before belching loudly. Nice.

Time for Sunday dinner ... which is very awkward due to all the ongoing feuds in the house. The Situation declares it "wrong" that Deena stole someone (boy or girl) from Vinny's bed. Deena accuses The Situation of being a hypocrite given his record of trying to steal girls from the other guys. She has a point. Pauly then decides Deena must be punished with a prank. The prank is moving Deena's bed out of her room. "Why would you do that?" a very mom-like JWoww asks Vinny and Pauly. "That was malicious ... I don't want this girl having a mental breakdown." As if on cue, Deena begins to weep.

JWoww attempts to play peacemaker by bringing the pranksters and prankee together. Pauly then gets very serious, accusing Deena of being a different person who can no longer take a joke. "You've changed -- not me," Pauly says. "I haven't changed since day one. I'll never change. Ever." We believe him, too. Deena then admits that she might -- just might -- be drinking too much, which leads to her doing dumb things like stealing hook ups from Vinny. Pauly and Vinny then accept Deena's "apology" -- and all is well.

The next morning, Deena, Snooki and Pauly head to their first day at work at the pizza parlor. Pauly D gets the dream job of passing out fliers on the street -- an excellent way to meet women, apparently. Sure enough, he is soon yucking it up with a number of customers while Snooki and Deena slave away at the pizza assembly line. It's far too much work for the ladies, so they pay a customer to sneak bottles of wine into the restroom. Soon, Snooki and Deena are chugging red wine while their boss pounds on the door. "We're coming!" Snooki yells. Thinking quickly, Snooki offers an excuse as to why Deena needs to be locked in the bathroom: "She just has her period!"

Meanwhile, Ronnie is still talking on the phone to Hannah from Long Island -- even though he is apparently back with Sweetheart. This does not sit well with JWoww, who confronts the big man about his plans. Ronnie is more or less unresponsive. It is implied that Hannah might be coming to visit, too. Uh oh. Back at the pizza shop, the boss has discovered half-filled wine bottles in the restroom. Snooki and Deena deny that the bottles belong to them. The boss then makes a show of pouring the remaining wine in the sink. "That's definitely alcohol abuse because I could've drank that," Snooki says.

Back at the house, Ronnie has bought Sweetheart an outfit -- one that he picked out himself. "I'm just like completely head over heels in love with Ron," says Sweetheart, who knows that Ronnie has "changed." Oh boy. JWoww and Snooki then head to dinner and discuss how much they miss having sex with their boyfriends. JWoww suggests making a mold of Jionni's, er, anatomy. "I might do it -- turn Roger into a vibrator," JWoww says. The conversation soon turns to Hannah. Snooki advises JWoww to "let it be" -- based largely on Sweetheart's violent reaction a few years back when the ladies tried to intervene in her relationship with Ronnie. Fist-flying flashbacks suggest that Snooki is probably right.

Night falls. The entire gang heads to the club. Funny how Italy looks exactly like Jersey and Miami from the inside of a club -- right down to the inevitable Ronnie-Sweetheart feud. "I'm dancing three feet above some fat chick and Sam is giving me a dirty look," Ronnie tells the camera. Indeed, Sweetheart looks ready to hurt somebody. "This isn't going to work because you don't trust me!" Ronnie screams at Sweetheart. He then storms out of the club. Sweetheart is heartbroken. It's all very, very familiar.

The Situation and Pauly, in the meantime, bring home a pair of ladies ... but Pauly's blonde is not DTF and interrupts The Situation and her friend. The ladies then leave. Fortunately, The Situation has a "back up plan for my back up plan" and calls blond Britney, who agrees to come over ... at 4 a.m. CUT to Sweetheart, who is still arguing with Ronnie. She tells Ronnie that The Situation told her that Ronnie had other girls on the way to Italy -- and that she was able to "brush it off." Ronnie, however, can not do the same upon hearing that The Situation has betrayed him. He announces that he is going to confront The Situation -- and, to prove his seriousness, removes his shirt. It's ON.

Soon, Ronnie is screaming at The Situation. "You wanna be a bitch?" asks Ronnie before trying to flip The Situation off the couch. Naturally, The Situation denies ever having said anything about Ronnie's various back up plans -- even though a FLASHBACK clearly proves he did. It doesn't matter anyway because Ronnie is no longer listening. He goes to The Situation's room and begins throwing his furniture around. Ronnie is officially Hulking out. Then The Situation begins SCREAMING, too. "You want to hit me!?" The Situation screams. "Let's do it! Let's do it!" So they do it. A furious fight erupts ... and the show ends with a teaser for next week featuring ambulances and stretchers.

To be continued.
