Spazpants is checking the map as he tries to clarify directions that she now claims never to have given. "You think I'm insane?" he asks her. Good Lord, where to begin.
Gus and Hera start looking for buoys. For some reason, Gus believes that he has some specialized knowledge that will come in really handy here, though I can't imagine what it is. And elsewhere, Avi and Joe...are still looking. Meredith and Maria aim for the ice climb. Don and MJ, driving to the climb, are having a different problem, which is that his seat appears to be reclined against his will, and he wants her to push it up for him. It won't push, though, so she ultimately snaps that he'll just have to put up with it until they get to the ice climb. "Just sit forward and go fast," she says.
And then, in a test of true love, we see Aaron take his shoes and socks off and wave his bare feet from the back seat in the direction of Hayden up front. And she is actually rubbing his feet while driving. I don't care how much you love the person; that's foul. It doesn't help, though, so he takes his foot back. And then he says his feet stink, and she smells her hand. Ewww. At least they can laugh about it. As Lena and Kristy check their map, they see that there's a highway route to the Blue Lagoon, and then there's a back-roads route, which is shorter, but they don't know anything about it, including what the speed limit is. Lena and Kristy ultimately decide to take the highway. Good call.
Spazpants pulls over for Blue Lagoon directions. I certainly wouldn't talk to them, and I don't think the people they accost want to, either. But the locals ultimately give up the information that the Blue Lagoon is right nearby.
Finally -- finally -- Avi and Joe find the buoy. They hug. They're very happy to see that they're headed to the pit stop at the Blue Lagoon. As they return to shore and hop off their boat, Avi says, "Aloha, welcome to the Big Island, everyone!"
