The series kicked off with Sammi 'Sweetheart' Giancola moving back into the shared beachside house in Seaside Heights, Ocean County, New Jersey, and she caused trouble immediately.
The atmosphere started when Sammi decided she didn't like new arrival and "walking holiday" Deena Nicole Cortese - who is friends with Nicole 'Snooki' Polizzi - and refused to talk to her.
Tensions simmered further when Sammi laughed at Deena for making a drunken advance at Michael 'The Situation' Sorrentino which he rebuffed.
The spurned girl then complains about Sammi and her boyfriend Ronnie Ortiz-Magro to the other housemates, which they overheard sparking a shouting match.
But rather than Sammi and Deena coming to blows it is Jenni 'JWoww' Farley who decides to fight Sammi in what appears to be a continuation of their feud from season two.
So that was 'Back to the Shore', who can wait for next week's episode 'It's Gonna Be An Interesting Summer'.
