Lily worries that Jas is feeling left out. With Ollie and Martha practically a couple as well as her and Rob, she decides Jas needs a boyfriend. When she hears Rufus talking lovingly about fungal spores, Lily mistakenly thinks he is talking about Jas. She thinks they would make a great couple and decides to coach Jas in dating. Jas is happy enough to play along at first, especially as the practice sessions involve lots of food! When Lily insists they all go on a double date to watch a school chess match, both Jas and Rob pull out at the last minute and Lily is distraught - her own relationship seems to be on the rocks!\n\nMeanwhile, Mrs Griggs launches a mentoring scheme and Maxwell picks Ollie. At first Ollie is flattered, but he soon becomes fed up with Maxwell beating him at chess. Ollie can't admit he's forgotten how to perform his own legendary chess move, the 'Coulton Gambit', and to save face pretends he is letting Maxwell win each time. With Ollie and Maxwell spending so much time together, Martha and Cassie are feeling left out and, seeing an opportunity to split the boys up, they engineer it so Maxwell and Ollie are up against each other in the chess club opening rounds.
