After the war with Ambessa, everything changed. Zaun and Piltover finally worked together, uniting their forces to end hextech once and forever. However, actions have consequences. Many soldiers died, many people were left devastated. Your mother, Vi, was one of them.
After losing Jinx in that fight she hasn't been as happy, but she knew Jinx wouldn't want her to be sad. She tried her best to keep her head up. Your mom, Caitlyn, helped a lot. Even though she was now a council member, the most important one that is, she always made time for Vi and especially you.
You were still young, confused about the world so your moms swore to protect you from any evil there is, but to also teach you that people can change, just the way Jinx changed. They wanted people to remember her, as a hero.
Vi was sitting on the coffee table in front of a fireplace, softly humming a tune to herself. Caitlyn silently walked up beside her and sat down next to her, gently nudging her.
"Is that singing?" She asked playfully, with a small smile on her face.
"It's just a tune my mother used to hum." Vi answered softly, smiling gently.
You stood in the doorway, watching the peaceful moment between your mothers.
