well in Scottish myth men steal Selkie's seal pelts so they can wed them but once they find it they instantly leave them and their child. But if the man actually has a soul and treats the Selkie with compassion and love they will help guide them when stuck in sea. So possibly you can have a Selkie via stealing the pelt... like a heartless a-hole
She makes her persona sound like the opposite of a thief, not like im upset, i just dont want her character to to counteract the story.
Her persona focuses on her wanted to help everyone she can, considering she feels helpless and weak.
