UPDATED EVERY TUESDAY The imposter has been here for a maximum of two hours and Derek already knows too much about him. "Dad. Dad. Dad. No. Dad. Please just. Dad." One-his dad is extremely worried about him. Extremely. Two- "No, I did not ask you to do that! Dammit!" -he talks to inanimate objects, usually when he accidentally runs into them. "Fucking stupid, Stiles, can you get any worse?" Third-he talks in the third person. A lot. Fourth: his name is Stiles. Like what the hell? His house is being inhabited by a living person named Stiles. Looks like Derek's finally got something to be angry about. Or....in which Derek is a ghost and Stiles is living in his duplex. *Just Like Heaven AU* Originally posted on my AO3, LessonsFromMoths
