Have you ever wondered why Anna fell in love with Hans at first sight?
Yes, she was desperate from a life of isolation.
BUT. Hans helped her up and asked her if she was all right. He made her feel special. The only male in her life to do that before was her father, who Hans looks sort of like a younger version of.
So maybe… Just maybe… Anna saw her dead father in Hans’ eyes and it wasn’t just that she was crazy desperate for love, but that she was missing the father figure in her life that had been taken from her so suddenly.
