Raleigh spends all of the stupid History of Magical Conflicts class trying to distract himself via note-taking and textbook-reading, rather than actually meeting anyone. Oh well. It's not as though his father could actually criticize him for avoidant behavior that consists of 'actually paying rapt attention in class.'
Afterward, he briefly mentions to Malik that he'd be happy to share his notes with her later if she wanted - there, maybe that will make up for his earlier social awkwardness - and then flees cafeteria-ward. He's looking for Marcy, or failing that for anyone else he recognizes from Boston who might know where Marcy is, because whether or not it's a GOOD idea to tell her everything, he so, so badly needs someone to unload on.
(Someone less affected by the situation than him, rather than more - Mother drilled into him that it's very rude to complain to someone about something if they're worse-hurt by it than you are - and that means he can't vent to anyone else from Sacramento, since he's the only freshman inductee. He could try to vent to Shannon but it would upset her and he doesn't want to do that and also Marcy at least already knows something is up.)
Does he see her on his way to the cafeteria?
