At Kate's birthday party, confrontation erupts when Mia storms in and claims the dress, earrings and shoes Kate is wearing belong to her. Guests turn on Mia, demand she kneel and apologize or be kicked out, and mock her earlier offer to let Kate borrow her things. Nick is urged to leave the room as arguments escalate. Mia refuses humiliation, insisting on her ownership and threatening consequences while another guest mentions breakup as leverage. The party dissolves into orders to leave, and Mia, stunned, is asked, "Are you acting like this because you want me to marry you?"
