Zack comes face to face with old friend Brett ahead of a discussion with Ravi (Aaron Thiara) about a pay rise at Walford East, and is left rattled by his presence.
He soon discovers that Sharon plans to interview him for a Personal Trainer role at Crunch Time, and is quick to step in and warn her off him.
