Letters: Buffy/Dr. Spencer Reid
Disclaimer: I don't own Criminal Minds or Buffy the Vampire Slayer.
I hope to actually get around to writing some Criminal Minds fanfiction, but until then fanart must suffice...
Crossover: Criminal Minds/ Buffy the Vampire Slayer
Pairing (Characters): Dr. Spencer Reid/ Buffy Summers
Dr. Reid writes his mother on a daily basis, telling her of his "adventures," but one day, through happenstance, his letter is received by a stranger, one Buffy Summers. The two become pen-pals of sorts, realizing how much their "jobs" have in common.
(In the back of my mind, Buffy was visiting a certain crazed slayer at the same sanatorium as Reid's mom and ends up with the letter by mistake. )
