I was amazed by the animation, rhythm and emotionality of this scene.
Perhaps Ekko deliberately called Jinx not just to fight, but invited her to play the way they did in childhood. In this way, he awakened certain memories in Jinx that made her use the tactics that she used when she was little, and then her actions became predictable for him. Including this helped Ekko, finally, get ahead of her.
But he didn’t realize that if those memories were still alive in the depths of Jinx's heart, then Powder was still alive too. And maybe Ekko was ready to take revenge and finish off Jinx...
The way the creators of the series showed Jinx deserves special attention. They didn’t romanticize her mental illness and didn’t make her just a reckless-fearless-funny-dangerous shooter. They showed us how terrifying it is to go crazy and how hard it is to live when the real you is slowly dying under the weight of loss and pain
