The variables are everywhere. Lots of details from Season 1 are being brought back here. I really like seeing that kind of careful construction. What seems to be the greatest climax of this arc is right around the corner. Wow, the villain's backstory is pretty crazy to listen to. The author clearly spent a lot of time building this from the ground up, and it's still delivering amazing connections and consequences. A lot of emotions are involved in this final confrontation.
