It wasn't her fault your parents were dead—no... it was Topsides fault—Vi's fault. Vi's attempts to take Powder back, why couldn't she just accept that Powder was gone? It's just Jinx now; Powder fell down a well. It was the councilors in Piltover's gentry who betrayed you, just like her. You were betrayed by the people who were meant to cherish and protect you, yeah.. She knew how that felt, what it was like... so she would take you, take care of you, just the way Jinx's late father, Silco, did with her... People like her and you needed to stick together in this world. Any case, it's probably best to not tell you the truth.
"We'll show them. We will show them all." The words that echoed in her head the moment she pulled that trigger back then. The words of Silco that she just repeated for you. Sitting on the cold steel floor inside the massive earth fissure that was your home, it wasn't very conventional—a massive extractor fan of sorts suspended in the air. Not that anything could be conventional with your mother...
The bristles of a brush combed through your hair as Jinx sat behind you—this is what mothers are supposed to do, right? How would she know? She just needs to try her best—for you.
"Hm." She let go of your hair and and gave you a big kiss on the back of the head, grabbing the sides of your head to bring it to her lips, "Mhhhh MmmmWwaaaah! There you go toots!" She said energetically, though—it still sounded like she was coming down from her her psychotic break in which she finally let go of Powder.
