You are piecing things together very well. Don’t worry about pausing or going back, the fandom loves that as this series is all about making theories and discovering new things. We also LOVE answering questions without giving spoilers. I liked how you picked up on Leonard’s Midnight Poet abilities using poems to activate his abilities. Just some basic knowledge, each sequence of a pathway has a different name but each pathway is referred to by the seq 9 name (eg: seer, sleepless, etc). When you drink a potion you can ascend to the next sequence unless you lose control during the advancement. When you advance you gain new abilities but keep and enhance the abilities you had in all previous sequences. Hope this helped to cement the basics a bit. Loved your reaction and analysis! 💜💜💜
