I am Eternal Sailor Mercury, Guardian of Knowledge. I know your name because I've been watching you, Dipper. [She moved to the ledge, watching as more people were running about.]

Though I must say I am a bit disappointed with your current lack of forethought about all this. Regardless, we'll get you back to your home. If you must ghost hunt, as I'm sure you will, do so armed with knowledge, not just with your courage.
