Andy & Tommy are the first to depart and note that the other teams "aren't smiling as much" at them anymore given all their leg wins. Ernie & Cindy are next (and still unhappy at having last week's first place "stolen" from them). Bill & Cathi, Marcus & Amani, Laurence & Zac and Jeremy & Sandy follow.
After flying from Africa to Amsterdam, Laurence has the brainwave to then travel to Denmark via London, meaning that he and Zac will arrive in Copenhagen around 8.30pm that night. Cindy & Ernie suspect something is going on but father and son remain tight-lipped. "Super shady...." says Cindy. She and Ernie join Bill & Cathi on a flight that gets in at 11pm, while Andy & Tommy and Jeremy & Sandy catch a flight that arrives 10.30pm.
Unfortunately for Marcus & Amani, they seem to think everyone will be getting a flight together the next morning at 8.20am, so they don't look for earlier flights and spend the evening chilling out at the airport.
Laurence & Zac arrive in Copenhagen first and head to the bell tower listed on the clue. Frustratingly, it doesn't open until 7am, which means a night sleeping outside while all the other teams bar Marcus & Amani catch up.
Meanwhile, it's time to board the 8.20am flight in Amsterdam for Marcus & Amani and they've finally realised their mistake. "Everyone is on the next clue and we're sitting in an airport," says Marcus. "We're out of the race."
Once the bell tower opens, the other teams have to climb more than 400 steps and piece together their next location by using a flag at the top of the building and a banner on one of the roofs below - Frederiksborg Slot. Sandy & Jeremy are the only team not to suss the clue, instead using a map of locations at top of the bell tower to incorrectly think they are going to Rosenberg Slot (which turns out to be a restaurant).
While Sandy & Jeremy figure out their mistake, the other teams race off to the castle where they find a roadblock waiting. One team member has to don period dress and learn a "complex three-part" dance.
While watching Ernie and Cathi attempt the routine, Bill recounts to Cindy how he met Cathi when he was 13 and she was 12 and they married after graduation. Cindy, in turn, tells him that she met Ernie in a bar. Ernie and Cathi complete the dance routine fairly quickly, later followed by Andy, but poor Zac is struggling to get the moves right.
Sandy & Jeremy, meanwhile, have met up with Amani & Marcus at the bell tower after returning to fix their mistake, although after getting the Frederiksborg location both teams suffer problems with directions and have to ask locals for help.
While they are struggling with directions and Zac is struggling with his dance, it's on to the detour for the other teams. The choice is 'all hopped up', which involves leading an adorable bunny rabbit through an obstacle course, or 'all churned up', which involves making six slabs of butter.
Ernie & Cindy go for the butter and get their next clue fairly quickly, directing them to a windmill where a double U-Turn is waiting. As much as they hate to use it, they decide to U-Turn Bill & Cathi, who were at the butter detour with them. "I want to win a leg, I'm sorry... you can't be nice anymore. It's a million dollars," says Cindy.
So, while Ernie & Cindy dash off to the pitstop, Bill & Cathi complete their butter detour only to realise they'll have to do the bunnies as well. They decide to U-Turn Laurence & Zac in turn because they know they are somewhere behind.
Zac, meanwhile, has finally finished the dancing (leaving Sandy & Jeremy and Marcus & Amani behind), and he's arrived at the detour with Laurence. They choose butter, while across the way Bill & Cathi have finished their additional bunny detour and are off to the pitstop.
At the pitstop, Ernie & Cindy have arrived first and won a trip to Fiji, while elsewhere Andy & Tommy have finished their butter and the two remaining teams at the castle have completed their dances. Unfortunately for Sandy & Jeremy, they get lost on the highway which allows Marcus & Amani time to race ahead to the detour, where they choose the bunny option and nail it pretty fast.

It's also bad news for Laurence & Zac who are having to complete the bunny detour after discovering they have been U-Turned. "This is bloody ridiculous," says Laurence. "This is a joke." Nevertheless, they complete it quickly and also head off to the pitstop, where Bill & Cathi have just checked in second, followed by Andy & Tommy and Marcus & Amani.
But, while it seems Sandy & Jeremy are a dead cert for last place given their navigation problems en route to the detour (which they are still doing), the same problem arises for Laurence & Zac - they are lost on the freeway, heading in the wrong direction and stuck in traffic, which gives Sandy & Jeremy time to complete their detour and overtake them on the way to the pitstop...
Laurence & Zac are eliminated from the race. "It's been a real honour to have Zac on the team," says Laurence, while Zac says: "It's been great to run with my dad. We had a great time."
