"The lost arts of a dead civilization. Very mysterious." Reinforce wiggled her fingers very nondemonstratively. She actually wasn't opposed to teaching him something back in principle- though it would be strange to do so without unison- but she remained wary of giving anyone information that might allow them to manipulate her/the Book.

"I'll try to make it." If she ran into a skirmish like last night, she might end up otherwise occupied. To her this was mostly to satisfy curiosity... a very strong curiosity, but not so strong as to supercede her responsibilities.
