I created a little comic strip inspired by an Arcane scene from season 2.
In my first watch, I interpreted Sky's dialogue as referencing the fact that she is a bystander in Viktor's life, even if she tried differently, he still didn't acknowledge her as much as she desired. We didn't even see him read her notebook in season 2? I was shocked at how much attention they gave it. It seemed like it was going to symbolize their relationship, Viktor recognizing her, etc. Now I wonder if it was meant to demonstrate how devoid their bond was that he didn't even have the capacity to read and act upon her studies. Instead, they'd both rather live in an almost fantasy-like dimension where they could likely ignore all problems and focus on "healing" others.
Just a thought I may be delusionally searching for more because I am sad the show ended LOL.
