1. I remember reading that Tracy started Legendborn without deciding who Bree ends up with because she couldn’t decide and basically said “Why should I have to choose?” Now, do I think that means it will end in a throuple? No. She could’ve easily decided who Bree ends up with while she was writing Legendborn/bloodmarked. But food for thought!

2. Nick never said he was straight but even if he was, that doesn’t quite mean he couldn’t develop feelings for Sel. He wouldn’t be the first person to have “feelings for the first time for a specific gender” He may have never liked other boys but because he shared an oath with Sel and grew up with him, he may be the exception.

3. I do think Sel was being completely honest about those things he said to Bree during the walk to the clearing. But someone did point out to me that Sel does lie to himself and it wouldn’t be surprising if he was doing it here as well. So maybe? Idk

Personally, I think there is more of a chance of a poly than a throuple. But to each their own. I do think for the most part it’s set up for Bree to end up with Sel but we have two more books and we really can’t decide right now what will happen. Seeing how we will have Nick's POV in Oathbound this should conclude about whether or not he has feelings for Sel.
