'The Great Unwashed'

Cherry dreads the day ahead when she realises that she's working alongside Zara at the Campus Surgery. She tries to keep her head down and stay out of harm's way, but finds it difficult to remain calm when a sleep-deprived Zara seizes every opportunity to antagonise her.

Zara's teasing is harmless, but Cherry's guilty secret becomes too much and she finally cracks, launching into a character assassination on Zara. Cherry reveals how even Daniel thinks Zara is a nightmare because she's always nagging him.

When Zara laughs it off, Cherry packs her final punch and tells Zara how she slept with Daniel in the consulting room. It's like a body blow to Zara, but she fronts it out - it's just sex, it's not important. Cherry immediately feels dreadful and tries to apologise, but Jimmi comes to whisk her away for dinner. Alone, Zara finally breaks down, absolutely devastated…

Elsewhere, it's Jack's first day at the Citizen's Advice Bureau, but his ego gets in the way of success.
