lyra probably had a lot of glaringly obvious signs that was she was more stressed and troubled than she needed to be when she was younger considering the breakneck effort she was putting in to keep up to her own standards and with rae but she was/is very much a "stiff upper lip" type so she'd never have opened up about it but having an instructor at the academy that actually seemed kind and chill compared to everyone else would have stuck out to her so i'm sure he'd have been on her shortlist of favorite instructors
