I think she’s really taking stock of the things she’s done and responsible for, and I think Season 2 becomes a period of reckoning for her.
I think she was confronted with her behavior, and I think he [Layton] was a real catalyst for change in so many ways on the train and for Melanie as a person.
She’s continuing that journey of exploring and taking responsibility for the things she did.
She’s in the process of getting back to the person she always was and sort of fulfilling her ultimate mission which was to be in charge of the science on the train.
