One of my favorite headcanons about Jinx and Vi is that Jinx secretly keeps a tiny, crumpled drawing of her and Vi as kids tucked into her belt or pocket at all times. It's like this fragile little piece of her past she can't bear to let go of, even as she spirals into chaos. The irony is that she'll set off bombs without blinking but treats this paper like it's made of glass. Meanwhile, Vi might act tough, but she still hums the lullaby she used to sing to Powder when she thinks no one's listening. It's those quiet, heartbreaking details that make their dynamic so layered.
Another angle I love is the idea that Jinx's 'voices' aren't just mental instability—they're echoes of Silco's manipulations, twisted into her own subconscious. Like, what if one of them sounds like him, whispering doubts? And Vi, despite her rage, still has moments where she sees Powder in Jinx's mannerisms—like how Jinx tilts her head when curious, just like she did as a kid. Those glimpses make Vi hesitate, and that hesitation costs her in fights. It's tragic how their bond is both their weakness and the only thing that might save them.
