Bad Blood is one of my favorite X-Files episodes, it was so funny and so quirky. And that definitely looks like Stull Cemetery . It could very well be, since the X-Files was also filmed in Vancouver. Actually in the newest season of the show they filmed in the same location that SPN used in a couple of season 13 epidodes (that abandoned shipyard), and that really tickled me.

Maybe you were doing a mash-up of Fresh Blood and Born Under a Bad Sign in your head?

Nah, you're definitely a prophet. Possibly. Probably? It'll be really awesome if they do end up having an episode titled Bad Blood in season 14.
