Tracy is determined to win Jake & his Dad Tom over. She realises that if she's going to impress them, then she needs to brush up on her skills at being around little brothers & dads. Taking advice from Justine, Tracy treats Tom as though he's a dog – throwing a ball for him to catch and rewarding him with treats.

Sick of always being ignored, little Hayley decides that it's time she made her presence felt. Everyone is shocked to discover the normally quiet Hayley stomping her feet, banging saucepans and chucking underwear out of windows! Satisfied that she's made her point, Hayley is soon back to normal. Meanwhile, Tracy goes through the motions with three sets of hopeless potential foster parents on a trip to the science museum.

There's a BBQ party to celebrate Justine leaving. Jackie goes to collect Grandpa to join the party, and is devastated to discover that he is in a wheelchair. Marco dresses up as a magician for the party but can't seem to do anything magic, until he pinches Duke's flip-flops while he is asleep and sends them up high into the sky tied to helium balloons with Duke waking up in time to see what is happening and then tries to catch them back down (but fails to do so) while everyone else is looking on with laughter. Jackie is determined that her Grandpa will still be the fastest Grandpa in the land and soon gets him wheeling at top speed. As Justine heads off to begin her new life, Tracy has to face the fact that she's the last kid from the old Dumping Ground set to be left behind.
