Much to the delight of the pupils, Waterloo Road's latest supply teacher, Jem Allen, cruises into the car park in her flashy car, as the drama about a Rochdale-based comprehensive school continues.
While Jem proves popular with staff and students, her upbeat attitude and glamorous lifestyle are enough to get right up Grantly's nose. Forced together on a school trip, their antagonism festers, and Grantly decides to call Jem's bluff by suggesting a detour to her house – expecting her to say no.
To his surprise she agrees and, when she lets them into an impressive country house, Grantly has to concede defeat.
Only fact-obsessed Karla is suspicious of the inconsistencies in Jem's stories. Elsewhere in the house, the boys take advantage by tucking into a few bottles of champagne from the fridge, unaware that their irresponsible behaviour is setting them on a dangerous downward spiral.
Grantly discovers that it isn't Jem's house after all but, before he has the chance to gloat, Paul raises the alarm that Bolton has hit his head in the swimming pool. Grantly dives in to rescue Bolton.
Elsewhere, sick of the attention her breasts are getting, a confused Janeece takes desperate measures to appear modest. Finally, she decides that she won't feel better about herself unless she has her breast augmentation reversed and returns to the "real her".
Meanwhile, with the exams in full swing, Chlo realises how much motherhood is going to restrict the future she wants. She forces herself to admit to Donte that she isn't ready to be a mum – she wants to give the baby up for adoption. A stunned Donte walks out speechless, leaving a devastated Chlo alone.
