Vi and Caitlyn finally have the chance at a good life with each other, but Caitlyn suspects something her mourning partner doesn't. After scanning the maps, it's perfectly plausible that Jinx, Vi's sister could have evaded death. If Jinx and Vi reunite, it could make Vi completely happy, but Caitlyn fears that Vi will die searching for Jinx.
Mel has taken her mother's place. She never thought that her, the just, refined, former Councilor of Piltover, would run such a warlike place like Noxus. She thinks that maybe, if she tries hard enough, the people can possibly incorporate peace in their morals.
Sevika thought that her little family would last, but she was horribly mistaken. Losing both Isha and Jinx, on top of the stress of being a Councilor, has taken its toll on her. She can't bear to find people she connects to in fear of losing them as well.
Jinx is alive. Not well, but alive. She barely escaped the blast of her grenade with her shimmer-induced speed, dragging her heavily injured body through an air duct. Now, she's all alone again, inside of the tunnel systems. She doesn't know where to go, scrounging for scraps and barely making it through each day.
Ekko's returned to the Firelights, but a change has occurred. He had started to mend his relationship with Jinx, and after the news of her death hit him, he stopped finding joy in things. The young Firelights playing, the sunlight streaming through the tree, his hoverboard, all things that used to put a smile on his face, just seem to remind him of Jinx.
Jayce and Viktor are stranded in space. The blast from the Arcane destroyed their mortal forms, and now only their celestial bodies remain. They travel to different universes now, helping people when needed, or just talking about their memories together. The whole cult-exploding put a rift in their relationship, but they are mending and expanding it slowly.
