X-Files gets back into its old style human freaks when one of Doggett’s old cop cases gets released from prison. In true Doggett Style, he catches a man in a home with loads of dead people - so naturally, he did it.
Thirteen years later he’s released because the DNA at the scene didn’t match his. Doggett gets a little personal when he sets out to find out what’s happening. Naturally Reyes figures out that the killer has two personalities and the other has completely different DNA. It all rather sucks and nothing interesting happens all throughout the episode.
