Anna likes to think that she notices a change in Elsa, but if she's honest with herself, it's probably wishful thinking. The woman is just as quiet and meek as when they met. They still make a general pretence to avoid each other at home – even if Elsa always makes sure she cooks enough food for Anna, and Anna remembers to bring home a chocolate truffle every day from the bakery next to the hospital.
They cut it in half and share it after dinner, and Anna thinks that maybe, in another universe, they could have been friends.
