S03E17: Rachel asks Eddie to stay

Mika takes her eco-warrior plans to another level, with Brett, on the building site of the new Training Centre, as the school drama continues.

Oblivious, headmistress Rachel counters Eddie's plans to resign by winding him up. His mood later worsens when Steph shows him a bounced cheque from Hordley.

Rachel leaves Tom to deal with Mika, and says if he doesn't get through to her she faces exclusion. Leon, Mika's internet eco-guru, pitches up and they climb the threatened trees. Tom's incensed but Mika tells him to get lost, and Leon and his cronies smash the classroom windows.

Elsewhere, Chlo admits she wants Donte back. Maxine's advice is to make him jealous, and Chlo looks hot when she goes on a lunch date with Dikran. Donte can't keep his eyes off her. At lunch, Chlo's inspired by Dikran to set up her own hairdressing salon.

When he fails to get through to Mika, Tom storms off and bumps into Davina but is annoyed by her flippancy. Davina has a bad feeling about her relationship with Tom.

Eddie, meanwhile, takes a hard line with the pupils, but Mika won't give up the fight – it's now personal and she sees Tom as enemy number one. She lashes out when Tom tries to climb the tree, and he falls to the ground.

Hysterical, Mika tells Tom she's sorry. Tom tells both girls he doesn't want to stop them doing what they care about and he's going to be spending more time with them – consequently freezing Davina out.

Rachel asks Eddie to stay, but he can't get over the blackmail. Rachel's in turmoil and calls the council. Eddie can't hide his relief, but is she being honest with him?
