Good as Gold

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.
