Sokka's there. Sokka's not getting out of the car, because he can't seem to move -- and then he is moving, abruptly, throwing the seat cover down over what's on the back seat before climbing out. Toph shouldn't see her.

(It does not, at this particular moment, occur to him that Toph does not actually see anything.)

And walking quickly towards the bushes to throw up the entire contents of his stomach. Don't mind him, he'll be back in a moment or so.
