What do you think about Jinx and Vi in Arcane?

Jinx and Vi’s relationship in Arcane is one of the most compelling aspects of the series. Their bond is deeply emotional, layered with love, resentment, and tragedy. Here's what I think about them:
Jinx and Vi as Sisters:

Early Bond: At the start, their bond is incredibly heartwarming. Vi is a protective and caring older sister, while Powder (later Jinx) is a sweet but insecure younger sibling who looks up to Vi. They represent a team built on love and trust, which makes their later conflict so heartbreaking.
The Rift: The tragedy in Act 1, where Powder's mistake leads to the deaths of their family, creates a rift that neither fully recovers from. Vi's frustration and Powder's feelings of abandonment set them on separate paths, with devastating consequences.
Themes in Their Relationship:

Love and Loss: Despite their separation, it's clear that both Jinx and Vi still care deeply for one another. Vi wants to save Jinx from herself, while Jinx is torn between wanting to trust Vi and fearing betrayal.
Trauma and Guilt: Their dynamic is a poignant exploration of how trauma shapes identity. Vi feels guilty for leaving Powder, while Jinx internalizes Vi’s perceived abandonment, driving her descent into madness.
The Conflict:

Vi’s Perspective: She desperately wants to fix things, but she struggles with how much Jinx has changed. Vi represents the hope of reconciliation, though she’s increasingly outmatched by Jinx’s instability.
Jinx’s Perspective: Jinx craves Vi’s love but is consumed by paranoia and the belief that Vi has replaced her with others (like Caitlyn). Silco's manipulation only deepens this wedge.
Why Their Story Works:

Their story is powerful because it feels real. The mix of love, betrayal, and misunderstanding mirrors the complexities of real-life relationships, especially those shaped by trauma. It’s tragic because both characters want the same thing—each other—but their circumstances make it nearly impossible.
