It's Andrew's birthday, but no-one's remembered and he's still in the dog house over his dealings with Diana. Thankfully he's told Harry, who told Summer, so eventually the family find out and arrange an impromptu party for the tearaway teen. Natasha isn't happy that her boyfriend hasn't confided in her and resorts to making digs at Summer again, but she rises above it. Meanwhile, Paul confronts Diana about her plans to destroy him. Her boss Rosemary has told her not to act, but Diana has other ideas. So Paul suggests they can work together to take over Lassiters, but she needs proof of his allegiance to her. So he does the ultimate dirty deed and cheats on Rebecca with Diana. Then Diana reveals she has no plans to work with him after all, despite what has just happened, and as a guilty Paul heads back to his family, she unveils video evidence of their time together.
