When Imogen refuses to attend her Year Twelve formal, Doug plans a Willis family formal and invites Terese to join. Worried about Imogen's state of mind, Terese agrees to attend, hoping Brad's issues about Ezra can be put aside for their daughter's sake. And while the night initially goes well, the tension between Brad and Terese finally erupts leaving poor Imogen devastated.

Brad is distressed to learn from Paul that Ezra accompanied Terese to her room. He finds her alone but assumes the worst, ie, that she slept with Ezra and their marriage is over. After dealing with Ezra, fragile Terese can't reveal the truth (that she had to kick Ezra out). Josh is alarmed to hear his parents may split up for good and urges his dad not to give up on his marriage.
