Susan's looking up at the sky, hoping that somehow if he focuses on the sky and on flapping as hard as he can this will work, even though it hasn't yet. He must just be doing something wrong, he just doesn't know what... He even tries jumping as high as he can (which admittedly isn't very high) just to see if it helps, but it doesn't do a thing.

He catches sight of a branch out of the corner of his eye, and he's already looking to Strange by the time he suggests that. He doesn't want to stop, but it looks like really they should... He nods after only a moment's hesitation.

"Okay, stop then... We'll have to try something different!"
