'Grantchester' Season 5, Episode 2 Recap: Family Boundaries

Grantchester Season 5 continues with a theme, once again opening with Will on his motorbike. He's meeting Mum's boyfriend, St John Gurney-Clifford (Dominic Mafham). The good news is St John doesn't openly sneer at Will's chosen profession. Instead, he's faintly amused by it, which is rather worse, all things considered. Almost as bad as finding out St John is rushing to get Amelia to the altar.

Will heads back to take it out on the punching bag, hard enough that even Vic feels the need to ask what's wrong. Meanwhile, Geordie is already regretting inviting Cathy's mum Diana to stay, and Cathy is not exactly sympathetic.

Geordie: "There's only one thing that makes a person look more guilty than running away, and that's running away with bags."
