Phil and Brenda's flirting makes Carol and Stan's day even worse and Chloe makes an unwelcome discovery. Sarah, however, is happier, and considering starting writing again.

Stan's plans are wrecked by Carol's surprise admission. Chloe has a big decision to make. Self-sacrificing Sarah solves two expensive problems for Richard and Eva's big day.

The two opposite 'Grease' themed parties eventually merge into one, with a drunk Sarah embarrassingly misinterpreting Jason's invitation then misunderstanding Eva's reactions. Kieran's happy though.
