The Doctor was a good guy and Melissa knew it, if only she's being born as a human not a reincarnated being destined to end one whole species of supernatural creatures. Maybe, just maybe she will give him a chance to be next to her. She will give herself a chance to be with him, it sounded normal and in a twisted way peaceful. Being just a human, a regular human who live, breathe and get sick and die. A regular human with regular tasks, a housewife with children and a job and that her only worry was building a better future for her children, and be a loving wife, a happy human.
