"All right, Karlyn, you did the Great Wall, you can do this little bitty rock," Lyn says encouragingly. Tom and Terry leave in third, as Tom says, "Thank God it was you, not me." Well, now he's going to make you do the next Roadblock, silly. You should have told him you could have done it faster. Guilt, Tom, think guilt! Godwin starts up the rope. "All legs!" Erwin calls encouragingly. We cut to Sarah, who is tearing up in spite of her best efforts not to. As Karlyn starts climbing, Lyn talks yet again about how they're doing all this for their children. Continuing to not help, Peter tells Sarah to "pull the handicapped placard out and tell them you're next in line." She wipes away an actual tear and looks back up at the ropes. She's not complaining, she's not freaking out; she just happens to be worried, and probably feeling stupid for agreeing to do this, and probably afraid that she's about to repeat her experience at the Great Wall. She exhales in an effort to get herself calm. Meanwhile, Lyn calls out, "If you can have a baby with no anesthesia, you can go up this rock." The good part is that it makes Karlyn laugh; the bad part is: oh my God, enough with the childbirth references.

As Sarah receives her instructions on how to climb the rope, Peter is calling out inspirational hoo-hah about focusing. He has a hoo-hah full of hoo-hah, that is for sure. "Peter," she says sharply, "shush, I've got to listen to the directions!" She starts up. Meanwhile, at the top, Godwin collects their clue. But as he starts back down, he's concerned that he can't even rappel, because his arms are so worn out from the climb that he can't hang on to the rope. Sarah mutters that she's caught in the ropes. Karlyn continues climbing, clearly having a lot more success than she did the first time around. For whatever reason, Sarah is talking to herself, quite clearly, but she keeps using Peter's name. "Peter, wait, I can't -- Peter... " And then she gets nervous and says, "I just can't!"

Unsurprisingly, when we return from commercials, Sarah pulls it together. She gives herself that "find your power" instruction again, and she starts back up.
