Piltover Jinx, Vi, and Cait

With the release of the Vi+Jinx cover from Nicki Taylor and Lunity (i believe) I’ve had the thought come back to me.... “What’s the deal with Cait, Vi, and Jinx?” I know the general information like Caitlyn recruited ex-gangmember Vi to help catch Jinx. I honestly love all three of these champions as i enjoy my adcs and junglers. But the atmosphere over these three have really gotten my heart. Is there anymore Official lore about these three apart from their champion backstory?
