I think jinx may have told Ekko she was leaving Zaun...

So I had the thought that with all of the content that had been cut I think when Ekko finally got through to Jinx and they talked things through she might've said something along the lines of "I know you still have so much to do here and I couldn't ask you to leave with me but I'm not sure who I am anymore. I've lost so much of myself here and I want to grow as a person and someday maybe I can become that perfect version of powder" then Ekko probably chimed in with the same line that Silco said "Don't cry, you're perfect" with the way everything wrapped up and the context clues we received it's clear that some sort of conversation happened regarding her departure and Ekko is the only one who would actually know where she's going for multiple reasons. Their coordination and their aesthetic showed that of a couple that is willing to even allow their blossoming relationship to continue from afar. Considering they are both talented inventors they might've even came up with some form of long range communication device for them to both use to keep in touch.
