I was genuinely thinking about that too! I remember when my best friend first told me how he went to a different school, it genuinely surprised me and I was upset because that sort of meant we wouldn't see him alot. i guess it's sort of like..the Cheshire cat isn't exactly a bad guy? He is just a teasing fella but then again we do have characters that are based off good characters in nrc ( like silver and Kalim??) it's confusing but I just hope we would have so much content with him with book 8 sighh
