I think this might be why, of all the new series’ companions, I don’t like Martha Jones.
Rose, Donna and Amy didn’t want to leave ‘My Doctor’, ‘Raggedy Man’ or ‘Spaceboy’, but they didn’t have a choice.
Martha Jones just walked away.
Martha’s family had just gone through a year of hell. A year of being TORTURED, a year where they were threatened with DEATH every day, a year where they saw horrors unimaginable. They needed her.
Martha herself just went through a year of hell. A year where she was hunted every day. A year where there was a special forces unit tasked with doing nothing but tracking her down. A year where she saw an entire country burn in front of her eyes. A year where she witnessed more death and destruction than any one person should ever have to. A year where she saved the universe not with magic TARDIS/Metacrisis/Universe crack powers but with her own brains, cunning, determination and willpower. She needed her family.
She had also just spent a year in love with a man who didn’t love her back. A man who was often dismissive of her thoughts and feelings. A man who she had to watch fall in love with another woman and accuse her of being his executioner after two months of going from being a doctor to a maid in an era when she was thought of as less than a person because of the color of her skin. Then three more month of working in a shop to support him. Her thanks for those things was “thank you” and a hug. She went through a year where she TIME AND AGAIN proved herself, delivered the impossible and yet was judged unworthy just because she wasn’t someone she’d never met. And THEN the year of literal hell.
Put yourself in her shoes for just a minute.
She made absolutely the right decision, for her own mental and emotional well being, and for her family’s. She still cared for him, she gave him a lifeline back to her, but she couldn’t survive in that environment anymore, having her self esteem torn down every day after she had proved over and over just how amazing she was.
