She taps the faint mark on her forehead- if he knows Felix, surely he'll recognize it as being the same as the mark that's recently appeared on his forehead- and traces out the Charter mark for light, letting it flare before flicking it up to rest on the ceiling, where it illuminates the area as brightly as an electric light would.

When she speaks, her tone is the same one she used as a prefect to explain things to underclassmen.]
