In this promo for the Season 5 finale of The Real Housewives of New York (airing October 1), Ramona Singer and Sonja Morgan dig up old fights, Heather Thomson unleashes her resentments towards Sonja, and poor George gets in one more insult at Ramona.

It wouldn’t be a Housewives finale without a whole lot of name-calling, and this time, it’s Heather’s turn. Most of the action will take place at Heather’s charity fashion show, where Aviva Drescher walks the runway.

Off-stage, Sonja will bring up the awkward toaster oven photoshoot she did with Heather’s guidance, and Ramona won’t stop talking about George grabbing her arm in Season 5, Episode 17: “Don’t Make Room For Daddy”. At one point, Heather tells Sonja, “Take your ungrateful ass and get out of my face.” And Carole Radziwill? Well, she just tries to “calm down” a seething Ramona.

Yikes! Check it out below.
