What a great crossover, and another fic in which it's not necessary to know TW to appreciate it. Genius plot, the idea that people were being killed in the future and their bodies brought back. And the perpetrator was an entire surprise to me. Really enjoyed Draco's role in this as well!
Mmmm, Jack Harkness and Harry! Oh yum, and Harry finally making a decision about who 'his man' would be. I love the idea of Harry's final occupation choice, and like Ginger, I do think that Harry one lucky sod, and I know he'll not step out of line, even if Jack is randy and can't help himself. Snape wins, hands down, even over this sex-ay competition.
Nailed your genres and prompt, oh yes you did! Great story and contribution to the Snarry fandom, Snitch!
