3 Works in Castiel/Tenth Doctor
In which both of them are ancient, and neither of them are in love with each other.
Doctor Who/Supernatural, Ten/Castiel, the wreckage of our lives, prompt, from comment_fic.
- Part 10 of Down The Gutter Drain
In which Cas knows The Doctor, Sam fanboys, and Dean realizes that he missed his window of opportunity
Warnings: Slash (minimal) Angst (lots..it's Dean after all)
