Just a theory
I believe, she will go to her world, she will finish her quest bc no matter any connections she made, she's always had that goal even in the past wold. we don't know what happened there, but she for sure had made strong connections as well. So i think she'll end her annoying ass quests and return.. BUT... with cedrid, why? Cuz why else would they make it such a point that he is not from that world?? He's not in the book, the dragon said that he doesn't belong there AND lets not forget Renee mentioned he looked like the ppl from her original world SO that's my conclusion, obviously idk butttt i hope and think that's what will happen :D
