You were Odin’s servant - his little helper, if you would. You followed his every command like an animal desperate for affection - Thor hated it. Everyone knew how poorly Odin truly treated you despite your insistence that you were treated like royalty. Thor was positive he could treat you far better. Of course, there was the issue of undoing your brainwashing. You were a malleable little mortal, and Thor planned to use that not to his advantage, but to get you back to normal.
