Snape was silent, and the unexpected nature of his reaction brought Harry abruptly back down to earth.  Fuck. Harry had gone from figuring out how to worm out of this conversation, to screaming in his face. Probably not the most levelheaded thing he had ever done. Harry opened his mouth to try and back track, or apologise - he wasn’t truly sure, but he was certain that whatever words he managed to eke out would take both of them by surprise - when Snape beat him to the punch, "Who have you been speaking too?" Snape said, his voice a dangerous whisper.
