Back from break, it turns out that the Cootes are stuck on Oatman, probably because they didn't set foot outside the RV while they were there and thus have no idea what it looks like. They make another wrong guess. Over at the DiSalvatores, Mason has taken over and is yelling at everyone but actually getting things accomplished. It appears that Mason is the only member of the family who knows which states are which on a map. Amy says that her son's brain is like a sponge, so she'll do whatever he says. Meanwhile, the Cootes will not listen to the kids, even though Jake is insistent that he is correct. They guess again, and again it's wrong. Both Jake and Cassidy know where to put the Drive-In cube, but Keith and Jennifer don't listen to them and tell them to shut up. Finally, Mason realizes that they're looking for Oatman for one of the cubes. Yes! Go, Mason! He gets the Oatman clue in, and then checks over his work. The last cube they need is the Midpoint Café.
And over at the Cootes, there is still more screaming and poor communication. Jennifer admits that they worked so well together in the past, but were "a mess" during this challenge. That's because you adults don't know the answer and you don't trust your kids to help you. The DiSalvatores have a guess! But it's wrong. They run back on the map and switch the two Texas cubes around. The Cootes aren't even close. The DiSalvatores press the buzzer ... and it's right! They won! I have no idea how! But it is glorious! Cassidy shrieks in anger, because the apple doesn't fall very far from the tree. Group hugs on the DiSalvatore side! "You guys suck!" on the Coote side. Aw, Mason is so happy that he doesn't know what to do but try not to cry on national TV and hug everyone. Even Reno gets a group hug. Gross. "How did they win?!" Cassidy asks. "Hey!" her mother says, as if Cassidy's behavior right now isn't her and Keith's faults.
Reno asks the DiSalvatores what the best thing they got out of this show was. Of course, they don't say the money or the delicious sensation of kicking Coote ass, but becoming a closer family that communicated better as the trip went on. And Amy credits her sons for the family's win. Silvio says this is the first thing he's won in his entire life, being a member of the worst sports teams. I have a feeling this is less of a coincidence, and more because of the fact that Silvio was on those teams. He really won this thing in spite of himself, and the DiSalvatores deserve this win just for having a handicap like Silvio. Reno has no idea how to speak when he sums up their trip: "when everyone thought you were out, you were not out. And when everyone thought you were done, you were not done."
