Whether or not Jinx and Vi are sisters is something players have been wondering about since Jinx’s release back in 2013. Her, “you think I’m crazy? You should see my sister!” line has had players putting on their tin foil hats, but Riot has never given us a confirmation, until today.
Riot Games design director Greg “Ghostcrawler” Street stated in an interview that the two are indeed sisters! Take a look before at the 1:13:33 mark.
This was caught by Reddit user l1sowski and posted in this thread, where people are losing their minds.
The two characters both have neon colored hair as well as strong personalities. Vi was in a gang before joining Caitlyn on the Piltover police force, and Jinx just has ... a fondness for mayhem. They do certainly balance each other out.
Vi’s lore is quite outdated and never mentioned Jinx, since she came around later, but Jinx’s lore did mention that she loved to pick on Vi. Her login screen was a busted up version of Vi’s and Jinx also had a line that mocked Vi’s theme song. Now I guess we know why!
