She's like me in that I let Hel take over too. Hel is very powerful.
But Hel was obsessed with Ty/Hod when she was in my head. Maybe now that he's gone, she's moved onto thinking about her dad? She didn't think of your dad as her father though. There was another Loki in her world, one that used a man named Colin as a vessel. He's never been on the island.
