Jody borrows or takes things from the other young people and Swedish woman Hilde from the council's planning department arrives to see how The Dumping Ground uses its space.
Floss finds plans for a luxury bedroom conversion in the attic and the young people argue over who should get it, so Alex decides they should compete for it, with Sasha and Chloe making the rules.
Floss copies Hilde's style and accent and at the boxing gym, Jody is initially unenthusiastic, but soon takes to it.
Alex and Charlie are the only remaining players left, so they decide to both remove their tags and Hilde reveals the attic plans are for a billionaire and it turns out she is not Swedish.
Mike and May-Li are surprised that Sasha received positive feedback on her work and Finn is left with the deciding vote on Joseph and Archie, however, he insists they end arguing and share a room.
Sasha vlogs her last day at The Dumping Ground and Dexter arrives for a visit whilst Floss returns from the hospital with crutches after chipping a bone in her foot.
Taz has to help Floss, but agrees as the injury was a result of using her rollerblades and Dexter is unhappy his things have been moved out of his old room as Joseph now shares with Archie.
Brothers Jay and Bird arrive at The Dumping Ground late at night, taking Candi-Rose's room, so she moves in with Chloe.
The young people have little expectation from Graybridge, but find out that they are intelligent and Mike embarrassingly explains how he knows Fiona to May-Li.
Before the race in the competition, Amelie tells Charlie that Fiona has made things great at Graybridge in her time there, but will go back to rubbish when she leaves.
Mike asks Fiona out for a coffee and Bird insists to Jay he wants to stay at The Dumping Ground.
Chloe and Sasha take a scan photo from the office, but accidentally spill juice on it and when Alex returns home to change his clothing, he tells Charlie and Finn about only doing washing up at Lily's café and all he has to look forward to, but they try to motivate him.
Floss is discovered to have cut the toilet rolls when she and Candi-Rose are declared the winners of the mummy challenge, but Joseph and Taz instead win.
People from the council's compliance and amenities department arrive for an experiment at The Dumping Ground that involves cameras being fitted, altering the interior layout and then arrange a stakeholder's meeting.
Steven observes the house from monitors set up in the shed as the young people delegate their communal areas, breakfast times and who should have the football pitch and the plastic sheets for divisions are put up.
Candi-Rose and Bird secretly arrange to meet by using the chessboard, but they are warned away from each other, despite their being no cameras, however, it turns out Floss and Jay were recruited by Steven.
The young people remove the plastic barriers, but Steven still believes boys and girls are better off apart and announces the girls will be moving to Graybridge permanently and the boys from Graybridge will move to The Dumping Ground, which results in uproar from the young people, Mike and May-Li.
The next day, the girls pack up their things, however, Steven changes his mind when Candi-Rose tracks down Julia, choosing to trust the young people rather than his study.
Taking tips from Sasha and Candi-Rose through a mobile, Jody tells Tyler about the holiday invite and asks if he thinks Brandon is being too serious.
Fiona speaks to Candi-Rose via videochat, asking for her to do her hair and makeup and in the attic, the boys reveal a surprise stag-do for Mike.
Back at The Dumping Ground, the young people gather in the living room and realise Ryan and Mike are not around.
Jody, Candi-Rose and Taz plan to hold Fiona up when it comes to her hair and make up and some of the young people are introduced to Henry on video chat.
