[@LadyRunic] You proposed him switching to Fall; I was working off that.  There was a scenario presented and I proposed possibilities for it.  You've also said that fey do change courts, though mostly ones that already live in border areas and without close ties.  Nyx's mother was from Winter, and given to Spring.  There was no escape involved.  Nor are the mara exclusive to fall.  They are in Winter too, and my understanding was that there tend to be a few of most sorts of fey in any court, even if it's not technically their native one.  Looked down on, perhaps, but present.

Sini herself is a halfbreed.  Her father was Summer, and it's well known.  Duska never had a reason to keep it secret.  You never mentioned any issues for her parentage.  Do I need to fix this?

Fey with relatives on both sides of a border would have every justification for switching.  You said it's uncommon, but not that it's such a death sentence.  I take it you are changing that?  If that's the case, I feel that there should be unsworn fey in the border areas, or "wild" fey: ones with allegiance to no court, thoguh they have to follow the rules of the land their homes fall in.

I'm not clear what you're talking about with indentured servitude here.  o.o  Or being ransomed back -- if they were captured, that's hardly switching courts.

From this it looks like Sorin's experience would have to be at the death of a leader and the resulting power struggle.  However, unless this was a /lengthy/ conflict -- or perhaps if there was a long period with many different leaders in short succession -- it seems like the last generals and captains of great renown would be dead, given that there's none left alive who saw Falk's rise to power.  That is, outside of the ongoing conflict between Summer and Winter, where there would be plenty of opportunity to shine.  This poses an issue for Sini and Duska.  Where did they get their experience and earn recognition?  I had figured there were at least raids, or.../something/, possibly of unaligned fey, possibly of disavowed fey from other courts.  Enough to be a serious threat in attacks.  That's the most feasible solution, I think.  If that's not workable, I'll need to think of something else.

As a note, I'm really not clear on what you mean by freely.  Duress isn't freely given, no matter how indirect the threats.  Would you please explain?
