Usually when people see Potemkin's arms, their first thought is not the applicability for hugging. It wasn't Potemkin's first either, and Potemkin has some shock at Wander's observation, at how he had missed it completely and yet so straight it is. Truly, this being must possess unique insight into the world.

"I've never tried so before, but it seems quite obvious now." Potemkin moves his hand off Wander's back, so the back of it is now under his feet. It seems rude to ask him to climb both up and back down.
