Siblings

When her doctor tells her she is dangerously unfit, Hannah begrudgingly heads to the gym, using her father's membership. There she meets Lucy, who introduces her to the world of women's rugby.

Jobless Dan has to be Marion's dance partner at her local salsa class, because she has threatened to stop his allowance from her if he does not.

Hannah embarks on a dating frenzy after signing up to the latest new mobile app - but the guys she meets are never as hot or cool as their profiles suggest.

Hannah and Dan's irascible father, Gregg, has organised a birthday party for himself - something that Hannah finds suspiciously out of character. When Gregg announces that he is getting married to human rights lawyer Beverley, Hannah is upset that he hasn't discussed it with her. Gregg explains that Hannah has ruined all his other relationships, so it's no wonder he kept it quiet.

Dan bumps into Holly Freeman, in a coffee shop. She was his crush in circus camp when he was 14. The pair are again attracted to each other and attempt to rekindle their relationship. However, Holly is eight months pregnant and the father is in Australia, where he impregnated her. Dan proposes to her in a restaurant; she turns him down and walks out.

It's the wedding day of Dan's best friend Jack and Hannah has joined him as his plus one. Dan's incredibly excited - he loves weddings, and this one is going to be pretty spectacular, as Jack is marrying the extremely wealthy Ophelia at their country mansion. Hannah can't wait to get snooping and see what life is really like for these Downton wannabes.
