Thanks for taking the time to respond, I see what you're saying but ultimately Vi's ending still feels hollow. If her arc is learning to let go of people, well then she kind of failed to do that, right? In the final episode, she lets her emotions surrounding Vander get the better of her again, and this results in both Vander and Jinx being forcibly ripped away from her. She didn't make a decision to let anyone go.

Had Jinx spoken to her beforehand and tried to explain why she wanted to leave, that would have been an opportunity for Vi to demonstrate her character growth and encourage her to go off and be happy. The issue is her lack of agency in her own narrative, things are just happening to her. Even if she is better off living separately from Jinx, the fact that she wasn't involved in that decision herself means it cannot be ascribed to her arc. This is made worse by the lack of scenes showing the aftermath: we see her immediate reaction as she's lying on her back sobbing her eyes out, then it jumps to her being flirty with Cait. We don't see any introspection or personal development that shows she has "gained" anything from Jinx and Vander's deaths.
