I haven't had much of an opportunity to look into it here yet, but I know for my own timeline - there's one where I die at the age of 16. Obviously I am from the one when I didn't. That changed when I was in a similar place like this one and it was not the same team that went on the mission to try to defeat the Yuuzhan Vong. I lived, and here I am many years later. In terms of your galaxy and mind - I'm not sure. Obviously my mother didn't have twins in your galaxy, and also chose to stop with just that first child.
All good Skywalker stories begin with finding a droid.
