I'll be posting some of Halsin's untriggered epilogue flag, read at your own risk. here you go; https://drive.google.com/drive/folders/1toM2E_7-cpiCvpvXQMjKt_Brh2ChhL2o
[spoiler]Halsin addresses a player to whom he's romantically linked in a private room in the Elfsong tavern. They discuss what comes next. This scene occurs shortly after the final victory over the absolute, a day or so after the battle. Player and Halsin are implied to have spent the night together.

Halsin:"When we joined battle for the last time, I did not want to presume we would survive. To feel your touch again seemed like a distant dream. That made last night all the sweeter.

PC: "Not to mention exhausting. I don't know where you get your energy from."

Halsin: "Do not be so modest - you gave as good as you got."

PC: (a)What comes now?
(b)Why do I get the feeling you're about to say goodbye?
[/spoiler]

There's a lot to shift through, its really sweet, one thing that caught my eye was
[spoiler]Halsin:"At last count, there were nine whole wagons of children in tow. They are my duty now. 'Daddy Halsin', they call me. Who am I to tell them otherwise?"[/spoiler]

This is in the game, but apparently it's the only line from this whole epilogue that made it in the game. This means this whole thing is bugged then since this is the only flag that got triggered.
The game doesn't acknowledge that you're in a romance with him, nor does it have his romance flag triggered throughout the ending. Definitely needs to be patched up much like Minthara.
