Hermione’s eyes shot open and she stumbled back from Draco who did the same, both of them looking like children with hands caught in the cookie jar.  Then there, standing at the end of the next aisle over were Harry and Ron with slack jawed expressions.  Harry’s face resembled something between horror and triumph, both which Hermione was trying to not think too much about.  Ron’s face was just straight horror, and that was to be expected from him.
