Ekko and Jinx doesn't make sense

Isn't it weird Ekko is into Jinx? She killed like... 3 of his friends (fireflies) literally in front of him. One of them had her back turned. And that's ignoring the sky high murdered-in-cold-blood body count.

Is it because of AU powder? Because powder in the alternative universe lived a completely different life to MU Jinx/Powder. It'd be like twins seperated at birth, going on to live different lives. They arent going to be the close to the same person even if genetically they are identical.

The whole thing just feels weird to me
