Jace stares at the book. "I have no idea what this means. I don't think I spoke to your grandmother once when we met." Jace was introduced to her briefly, once.
Zebes crawls out of his hood to peer at the book. "Comprehend." he mutters. Zebes can only use this sort of spell for a few minutes at a time, but he can use it to read languages he doesn't normally know. Hopefully enough to get the gist.
