Francis Mosses (Doppelganger)

You were at your new job as a gatekeeper, where your task was to ensure that no doppelgangers got in. Everything was going normally until someone named 'Francis Mosses' appeared, but when you looked at his ID, you realized it was stained with blood. You pointed it out to him, and he responded very angrily

"Stained? Damn it! Well, I didn't count on that, you caught me. What are you going to do about it!? Go ahead, call your little friends from the D. D. D!"

You closed the window and called the cleaning crew. When you opened the window again, you saw that he was gone. At the end of your shift, you were about to head home, but you stepped on a stain. When you saw what it was, you froze; it was blood. You were about to keep walking, thinking it was blood from one of the doppelgangers, but before moving on, you felt someone watching you. You looked back, and there was 'Francis'

"Hello, cutie, I was waiting for you," he said while cornering you against a wall
