Can I ask what the relationship between Orgus and Bela is like? How does Bela feel about her brother essentially running for the hills and how does Orgus feel about Bela shouldering the responsibility of the Alliance? Do they even give each other much thought or just live their separate lives away from one another?
As you might imagine - with them being siblings - its complicated.
On the one hand, by the time they grow up, the two understand each other quite well. They each know what made the other into the person they are. They both respect the choices they have made.
On the other hand... there's some slight resentment.
Bela came first, two years before her brother. Which doesn't sound like a lot, but because she was first, a lot of pressure was placed on her. Not by Corellan, but somewhat by other people. Even Kira.
Then Orgus came, and quite frankly had a much easier time of it.
From Bela's perspective, her little brother was a spoiled brat who got to run amuck while she pushed herself to live up to legacy of her parents. She drove herself incredibly hard, and working through that took a long time. If she hadn't had people in her life like Senya and Tasiele, she might have made some choices that she couldn't have worked through. So adolescence was hard. From her perspective, Orgus has always done whatever he wanted and been given a pass.
From Orgus' perspective, his big sister is everything the galaxy ever wanted Orgus to be. When he finally bolted, he was running from that as much as anything.
But - after reaching adulthood - they respected each other's choices. They respected they've chosen their own paths. And on rare occasions when Orgus does visit, he's great with his nieces and nephews.
And ideally, that would be the end of the story.
Until the day - many years later - Bela sent Orgus a holo-message saying 'Hey - Dad's sick. Come home.'
Orgus - half-way across the galaxy - is doing smuggler stuff. He replies 'Okay - i'll wrap up here and head back in a couple of days.'
It takes him four days total to make it back to Odessen.
Corellan dies after three days.
So - that leads to some tension. Because Bela, Kira and everyone else are at his bedside when he dies, but his son isn't.
Corellan tells Bela two things just before he dies. First, he tells her how proud he is of her. Second, for her to please not resent Orgus for not being there in time.
(Keep in mind this is all 'future AU', and subject to change.)
But - thanks for the ask!
