User blog comment:Robykirby/How old is Nora?/@comment-4010415-20140515233924

I think that all first year students, except Ruby, are 17. Just because Nora is shorter, it doesn't mean she's younger. I'm 21 years old, and I'm 5'0". There are 14-year-olds who are taller than me. When I was in 12th grade, there were 9th graders who were taller than me.

As for the rest of that, I always just figured that she has ADHD and is really immature and spazzy.
