Of course, the Gaghans also said later in some Insider footage, I believe, that Carissa really, really wanted to bungee jump on the race, so that was also part of their reasoning -- a statement backed up by the way we see her running down the steps calling out, "I want to do Fast Forward!"
The Godlewskis run into a guy who they ask about where to find buses. "This is an island," he tells them patiently. "I don't believe him, Trish!" Christine (I think) gabble-gabbles. Maybe it's a trick! Sharon calmly reminds them all that indeed, the place is surrounded by water, because they got here on a boat. Yeegawds. They finally realize that they need to get back on the boats before they look for buses, so they return to the dock. Paolos, Weavers, and Godlewskis are soon back in their boats, and then the Linzes, who don't love it that Mama Weaver yells out to the Linzes' driver to go slow. Wally and the Tonyas, and then the Gaghans, bring up the rear, getting back onto their boats. On the way back, luck takes over again as the Weavers, Godlewskis, and Linzes pass the Paolos, and the Godlewskis pass the Weavers. You can tell that nothing of consequence happened on the island, given that they were all so close together that their differing boat drivers result in a total rearranging of teams.
Anyway, the Linzes pass the Weavers, putting themselves in second place behind the pinks. Once again, transportation they can't control is king, and nothing really noteworthy happens on the boat ride back, other than one of the Linzes saying of Mama Weaver, "That lady needs to take her crazy pills." And you know where you get crazy pills, don't you? That's right. Waffle House.
