Millie tries on her Lunar Chick costume for Halloween. Lauren and Millie notice Tony is stressing over Amber visiting with her kids. Amber comes round and introduces Tony, Lauren and Millie to her kids, Fran and Jake. Things are awkward between Lauren, Millie, Fran and Jake. Sharon wants Craig to give fruit pieces out and Craig scares some young trick or treaters. Lauren and Millie aren't impressed with Tony's suggestion of taking Fran and Jake trick or treating. Sharon tells Mike that Craig is scaring the kids and Mike agrees to talk to him. Millie and Fran show each other their Halloween costumes. Mike realises Craig doesn't want to go out as he hasn't made any friends and Mike asks him to be called less scary. Fran and Jake discuss Tony, Lauren and Millie. Jake gets hyper on fizzy pop and accidentally ruins Millie's costume. Amber and Lauren are both impressed with Lauren's costume, but Tony objects to the lenght of the dress. Craig changes his costume to a zombie clown. Fran and Jake try to clean Millie's costume whilst Lauren dresses as a bin bag. Fran and Jake end up ripping Millie's costume. Sharon apologises to Craig for overreacting about his costume. Millie shows Lauren her ruined costume with Jake's pitchfork and Lauren is pleased as it means they don't have to take Fran and Jake. Lauren and Millie show Tony and Fran takes the blame for Jake, but Millie tricks Fran into telling the truth. Millie and Fran make up with each others and they dress up as Loser Chick and Human Ear. Lauren's outfit rips to reveal the dress on underneath and Amber agrees to adjust it. Craig goes trick or treating with some kids and Mike gets sprayed with crazy string.
