A story that acts as both Evelyn's departure story and a return to her while 6 is traveling with Mel. It converges on a lot of themes that 6 and Evelyn's arc together played with forgiveness and moving past the past for a happier future. It's not the most amazing story, but it's one that's filled with a ton of heart, and one that fans of Evelyn are sure to enjoy. Neither Mel or Evelyn overshadow each other, something that can be a concern with two-companion stories when one's not actively traveling with the Doctor. It's a nice bow to end 6 and Evelyn's adventures together after years of travel.
