2680: Mercedes and Sasha come to blows

Archie's freaked out when he finds the dead rat in the fridge and is paranoid that someone's out to get him. He accuses Lydia of playing tricks on him but she's not interested in his theories. Josh is alarmed when Archie tells him about the rat but as they talk outside the union, someone's watching them. Charlotte, Lydia and Josh join the party at The Loft as Archie and Dave arrive back at halls to find the door suspiciously open and the room in darkness.

Terrified, the lads make their way in and find the mannequin with a note saying 'your friend's first'. Archie's angry and convinced that Lydia's responsible, so he bursts into The Loft and confronts her.

Back at the flat, Hayley amuses herself by dressing up the mannequin until there's a knock at the door. Finding no-one there, she goes out to investigate, unaware that a cloaked figure has slipped into the flat behind her. Unperturbed, Hayley returns inside but she's confused when she finds the mannequin in a different position. On hearing a thud from the bedroom, a nervous Hayley heads to investigate - just as Archie, Dave and Josh return and come face-to-face with their tormentor…

Meanwhile, Gaz tries to befriend Lauren but he's shocked when she tells him that she wishes that he hadn't survived his attack. Newt sees them together and watches for a while, before heading over to check that Lauren's okay. He's shocked, though, when Lauren agrees to meet Gaz and tells Newt to back off. Lauren's suspicious that Gaz is trying to set her up and exacts her revenge by covering him in paint as she films it on her mobile. Gaz is left blazing with anger…

Sasha and Mercedes are still at odds with each other as they decorate The Loft for their Halloween party. Sasha's not impressed by Mercedes's choice of decorations and instantly gets her back up by lording it over her, while Calvin and Malachy try to keep the peace. Sasha's not happy that Calvin's employed Jake and is irritated by everything he does.

When Jake tries to save Mercedes from falling off a ladder and accidently grabs her bum, the two girls rally against him, until they remember that they don't actually get on, before continuing to snarl at each other. The night descends into chaos, though, when Mercedes and Sasha fail to see eye-to-eye over their Halloween props and both end up covered in slime.

Tony and Cindy take Holly and Tom trick or treating. Holly's amused when Tony arrives with Tom dressed as Father Christmas. Cindy, meanwhile, is excited to see what Tony's got for her. She imagines that it's a saucy vampire outfit but she's not impressed by her giant pumpkin costume.

Meanwhile, a friendless Darren is on the look out for a Halloween party and is highly amused when he comes across Cindy and Tony in the village. He can't resist a dig at Cindy's outfit but Tony quickly hurries them away. Unable to find a party, Darren finds himself alone in Relish but he's happy when Cindy, Holly and Tom turn up. At that moment, Darren realises that he's missed Cindy's company. When Tony arrives, he's slightly suspicious of Cindy and Darren spending time together and makes a point of taking them away.
