Hm. It only occurs to me now that he probably started moving as soon as she went into the invocation -- which easily lasts several times as long as the actual transformation. The "blip" change seemed to be about a half second at the most, and the invocation is maybe four or five seconds, based on my attempt to replay it in my head while looking at my watch. That would be enough time for him to get behind her, if he were reasonably (or superhumanly) quick.
