Up on the roof, Sitch deploys his patented sweatpants maneuver with the trick he's brought home. She takes the bait, as does her friend. Apparently the friend is a grenade, so Vinny pulls out a vuvuzela that he's re-purposed as a Grenade Whistle. Sitch returns upstairs to tell Pauly that the grenade is riffling through his things, but he doesn't care because he's dodging her at all costs. People start clearing out, so Vinny takes the opportunity to cuddle up on his girl. Just as he goes in for the kill, her uncle shows up to rescue her from this den of iniquity. And thus we say goodbye to Gina. She was the Juliet to Vinny's Romeo, or so he would have us believe. With that, the grenade decides to depart, too. Parting is such sweet sorrow!

As Sitch gets it in, JWOWW heads to Ronnie's side to talk about his most recent fallout with Sammi. Ronnie whimpers like a bitch as JWOWW says she went through the same guilt with Tommy. She assures him that he's a good guy and deserves to be happy. He continues to be flummoxed as to why she's punishing him and what he did wrong. Oh, Ronnie, don't get me started... JWOWW reveals that she and Snooki wrote the infamous letter last year because they thought Sammi would leave and Ronnie could go back to being his old, fun self. Instead, Sammi amped up her haggery by the power of a million, contributing to the household misery we are currently experiencing. Ronnie has a good, old-fashioned cry in the confessional, then heads back outside where everyone assures him he did nothing wrong. Which is a steaming pile of crap if I've seen one, but whatevs...

Pauly tries to turn the night around by lighting the candles on Ryder's birthday cake. Sitch also tries to turn the night around by getting it in. He asks Sammi if she has any condoms he can use, so she tells him to ask Ronnie. He lets it slip that Ronnie is talking to JWOWW, which sends Sammi on the warpath. She interrogates him as to what he's talking about and whether he's friends with JWOWW. He brushes her off, making her that much angrier. She comes downstairs, vowing to leave the house if Ronnie befriends JWOWW. All the while, the gang eavesdrops as they carry the birthday cake up to Ryder, who is passed out on the roof. Sammi joins Ronnie on the porch, asks him about a million more times if he's friends with JWOWW. When she refuses to answer, she lands a right hook on his chin and storms off. Cue the happy birthday song!
