There are times when Ms. Cameroon, due to her miniature stature, has some trouble reaching the classroom without being pushed or stepped on by passing students or other faculty members, which can really turn bothersome often. Luckily for her, whenever Theo follows her-which is often-she gets to avoid all that by riding on his shoulder as he gently holds her to prevent her from falling off (not that she cant hold on by herself, but hell, we are talking about his favorite teacher after all, he's extra cautious about her XD).
He was always known to be quite protective over the little Wartortle, out of both admiration and respect for her (also, he used to have a small student-towards-teacher crush on her during his first couple of years at the Academy, before he met Fey and Lorna). Wanna complain about the grade she gave you? Talk to him first. Have something bad to say about her methods or about her? He'll rip out your tongue. Wanna even go that far to hurt her? Don't even bother thinking about it, if he finds out you'd better be dead or having another identity. Messing with her is one of his berserker buttons, she did too much for him and helped him out many times, he finds it all his way of repaying his debt to her.
