*Eyes your post at the lake*

Just out of curiosity, how is it that Puck is at the lake at the same exact time she is in Quigley's office, right after the forest incident? Seems to me that you need to pick one or the other place to be, and seeing as how the Head Mistress and the professor are both aware of her being in his office now, I'd say she's not at the lake at this time.
