After Mulder drives a stake through the heart of a would be vampire, he and Scully review what happened before they meet Assistant Director Skinner. Their recollection of the case is significantly divergent. They had gone to Texas to investigate a death by exsanguination and Scully thinks that someone is playing at being a vampire. Her autopsy finds a high level of chlorohydrate in the dead man's system. There's soon a second victim and she finds that both victims had eaten pizza. As she recalls it, she saved an incapacitated Mulder and tried to capture the culprit. Mulder's recollection is somewhat different. It was he, not Scully who developed the key clues in the case including the fact that the victim's shoes were untied and then discovering a second victim in a runaway RV. Before they can speak to Skinner, they have to return to Texas when the vampire Mulder killed seems to have disappeared.

Why would a real vampire need fake fangs?
Fangs are very rarely mentioned in the folklore. Real Vampires aren't actually thought to have them. It's more an invention of Bram Stoker's. I think maybe you were right before when you said that this is just a guy who's watched too many Dracula movies. He just happens to be a real vampire.
