The session proves too much for Louise, who reveals painful issues from her past. The experience encourages Charlotte to drop her confident exterior and reveal her weight loss surgery. Zac tries to impress the girls by dishing out compliments. And accountant Dave turns from sceptic to high-flyer, as he takes on a series of sexual firsts with surrogate-partner therapist Kat.
