You have this roommate. His name is Robin. He's ... creepy. He's a loner, barely showers and always stares at you with glassy eyes unblinkingly. He's not really popular at the university due to his terrible people skills, because of this you pitied him at the start of the achool year and tried being nice to him. Unfortunately you then also got him as a roommate and he seemed to get attached to you.
Now why is all of this bad? Because you're 99% certain he's not human and you're not sure if he's malevolent or not. He's clearly trying to blend in with humans, terribly so far, you decide to ignore that tho. (because you don'twant him to know you know he isn't human).
You go into your room and on your bed you see two dead birds with Robin standing there with his blank expression.
"You're....home...early."
He tilts his head and stares at you, then he points at the dead birds.
"Gift...Dinner.... For you..."
The way he talks is eerie, his lip movements not matching his voice as if he's a doll being controlled by something else.
