Honestly, at that age I don't see one year making much of a difference, and it could really just be a matter of months in the grand scheme of things since everyone will have different birthdays. I'm thinking about aging some of them down too, just because I feel like I have way too many in the 22-24 range, though i may just keep the ages as a range in general. Who knows, human ages are so much weirder than wolf ages

(if you do decide to keep him shorter, I could totally imagine Maia calling him 'Sammy' and ruffling his hair a little when they pass each other in the halls. Though she may still do that if he's taller, I dunno, she's so freaking peppy)
Also can't wait for Emily, I still remember when I first saw your pic of her and my heart just pounding <3
And question for everyone because I'm curious and want to start figuring this out for my own characters:
What extracurriculars/clubs/sports are your characters involved in?
