Ruby and Jono have joint stag and hen dos and share their first dance, knowing they won’t get a chance on the day. The other sixth-formers join in, a special moment, the last time they’ll all be together before Jono and Neil head off...
Maddie is upset when Callum arrives and, overwhelmed by Jono’s flattery, kisses the groom-to-be with Esther watching in the back-ground! She warns Esther she’ll destroy her if she spills! Instead, Esther reveals Ruby’s plan to elope to the Osbornes so Ruby’s grounded!
While Jono distracts Jack and Frankie, Ruby climbs out of her bedroom window. But Bart lets everyone down when he’s stoned and without any wheels to get them to Gretna. Neil is promoted to Best Man and Maddie sees a minibus with the engine running – it’s now or never and the gang jump aboard.
Elsewhere, Esther tracks down Bart – they need to stop the wedding! A stoned Bart drives furiously to catch up with the minibus, they race side-by-side but when Maddie tries to slow down she realises the brakes aren’t working, they’re out of control. Maddie takes her eyes off the road to shout at Esther to slow down, but she doesn’t see little Leah step out in front of the bus. She swerves, but ploughs straight into Ste.
