The Doctor takes a stroll down memory lane; unfortunately, it's not a pleasant one.

If there was one thing she was terrified of, it was losing me. And after four years, vice versa. She was the one person I never wanted to lose, the one person I couldn’t handle losing. And I lost her. Jayden thought she was a perfectly normal girl who just happened to have weird dreams about being a completely different person, a gun shooting, ass-kicking Time Lady with the fake name Artemis. It's not until she meets the Doctor that she realizes that those weren't just dreams. As a Time Lady again, can she get over the pain of her past? Can she handle the pain to come?
