I think this just swap who dies? But maybe this actually get traveler killed, Since idk if they could beat scara at that point, and I doubt anything changes with Yae tho, I doubt she'd care enough about the gnosis to not trade it anyway. So Ig that just makes either Scara die instead, or Travler dies, and either way Siggy lives and The Fatui get the Elctro gnosis quicker, and CWOE is still sealed, witch means shes still around for the other nations and probs just continues as she was going from nation to nation gnosis hunting, I imagine if Scara dies then the story is largely unchanged.
