Fandom: Panic at the Disco/The X-Files crossover
Pairing: Ryan/Mulder, Ryan/Brendon/Spencer, Ryan/Jon
Warnings: CV (including dubious consent and implied violence). Deals with the Panic split.
Summary: But Spencer was right, it turned out, because a month later the bell rang again and there was Mulder standing on the step.
