He mulled over the question. Clearly determining how much to tell me. "His vision showed Arthur Weasley being attacked by a snake. Something that did happen last night." He allowed me to digest that information. How would he know it was a snake? That seemed very much something Voldemort would do. Also, where was Arthur to be attacked in such a manner? Clearly there was something going on that both sides were trying to achieve the same thing. "We were able to save Mr. Weasley. I brought Harry and Ron to a  safe place  in the middle of the night. I do apologize for not retrieving you sooner."
