From BBC Pure Soap:

Tanya organised games at the engagement party. Most party goers got drunk and played along. Geri and Marc were mistakenly put together in the ‘guess who's kissing' game. Melanie returned home to the news of her mother's arrest. She immediately told her dad that she knew Chrissy had been lying. Gary and Myra couldn't believe what she had said. Lewis helped Lucy ‘powder' her nose. After listening to her garbled monologue, Tanya and Sean deduced she must be on drugs. They decided they'd done enough interfering for one day. The police confirmed to Chrissy that none of the doctors they had questioned said Chloe had Hodgkin's disease. Chrissy broke down and confessed her lie!
