Question to Jaethals questline (spoiler ahead)

Greetings my fellow Queens and Kings of the Stolen Lands,

I have a question to Jaethals questionline in order to achieve a specific outcome. I tried to search the internet but didnt found a 100% certain answer.

So during her personal questline, I decided that I would reward her for her loyal service to me and my kingdom by allowing her to swap into her daughters body and turn to life again. Is there anything I need to pay attention to when doing Tristans questline now in order to prevent him from killing her later on?

Thanks for any answers!

Long may y’all reign!
