Ok so the jinx moment where you think she has powers is in my opinion a reference to what she has in the actual game where once Jinx gets a kill she ''gets excited'' causing her to get a massive speed boost
Stray Kids been doing lots of things from July 19th when the drop their last Album ATE which they did shows in Italy, France, Hyde Park and Chicago. The also got Japanese Album coming up. They also had a song in Deadpool and Wolverine called Slash also a few MV which had Ryan and Hugh in it. They also dropped the Opening and Closing for Tower of God which the opening is called Night and the closing is called Falling Up. They also start their tour in Seoul, Singapore and Melbourne Australia is Tomorrow here. Plus a few Fashion stuff.
thanks to Singed as it was shown in season 1 jinx managed to survive but now she has Shimmer in his body, that's why she permanently has its effects and that's why her eyes are pink now. We could even see the same speed movement during the finale when she struck Caitlyn
