Although Emily wants a small and simple hen do (bachelorette party), Pippa and Seb organize a surprise trip to Portugal with a larger group, including Pammie. Adam leaves for his stag do (bachelor party) in Las Vegas. Charlotte, Emily’s former close friend who engaged in an affair with Tom, is in attendance, although Pippa and Seb have no idea how she gained an invitation. Emily believes her hen do will be ruined by Charlotte’s presence; by comparison, Pammie’s attendance seems like a minor issue.

The hen do group arrives in Portugal, and the tour bus ride to their villa fondly reminds Emily of a trip she took with Charlotte to Cyprus years ago. Emily recognizes how much she has missed her best friend. She realizes she never adequately addressed her anger and sadness surrounding Tom and Charlotte’s affair. Sitting down to lunch, the group decides to play truth or dare. Charlotte picks truth and admits that her biggest regret is sleeping with Tom. She confesses that hurting Emily is the worst mistake she ever made.

Tess, Emily’s former co-worker, asks Emily if she was ever unfaithful in a relationship. Emily quickly answers no, but Pammie asks if Emily ever intended to be unfaithful.
