The Roadblock of Leg 4 of All-Stars required the racers to search through a pile of letters for one addressed to them, written by a racer from their original season. While Kandice searches through the pile of letters, she jokingly asks, "What if it's from 'Bama?", a reference to their rivals Lyn and Karlyn from Season 10. When they open the letter and find out it's from Lyn, they state that Lyn was the more friendly of the two. This statement was followed by a video clip from Season 10 of Karlyn yelling at Dustin & Kandice at an airport ticket counter.
