Last Tango in Buenos Aires

what happens

The final four teams now travel to Buenos Aires for a tango dancing challenge. The ice dancers apply legal sabotage to help them win the leg. Later on, Best friends Carrie & Devin finally confess their true feelings for each other, but it all does not end so well as Devin is then pushed off a cliff by the Sisters' emu and becomes seriously injured. Therefore, Carrie & Devin are forced to withdraw from the race but they get to choose one of the previously eliminated teams to come back to the race, so they choose the surfer dudes to take their place.
