Vi’s tattoos (Arcane)

Arcane Vi has these really cool tattoos but most of the tattoos are gears. Why tho? I think vi has gear tattoos because of her sister powder/jinx because when jinx was a kid she would make smoke bombs and nail bombs to throw at the guards. And on the back of vi is has the smoke that I think refers to when jinx uses the flashlight for her sister to find her. But that’s just an idea.
