Things that leaped out at me:
When she asked Adam "How can I help you?" on the Roadblock/Detour and then instantly came up with a way to assist, by laying out the blocks. I love that they worked together to get their pony where it needed to go. And the sheep-herding was really interesting, because it was a real test of calm. I love seeing them work together, and that there's never a focus on what Bethany can't do, but always on adapting and figuring out what she CAN do.
And I also got a good laugh when they came in second, and Bethany asked if they could go swimming but Phil told her that "the Puffin says the water's a little cold."
