Sounds like Hamish would have been somewhat familiar with at least a couple of yours. Mostly Marguerite and Justin, obviously. Justin would also probably have noticed that Hamish just...didn’t come back to school one year. Hamish is certainly not the mom friend but he’s not the troublesome one either. He’s the overly curious type that tends to be somewhat accident prone but with good intentions. I feel like they’d know one another and get along. Not sure if Hamish will have told Justin about being a werewolf just yet though. Depends on the relationship they had in school.
