all the avengers are reunited at the avengers tower, enjoying a party tony started. As bucky leans against the wall, casually drinking a whiskey and quietly looking at who's here, doctor strange walks next to him, his eyebrows narrowed, clearly on edge as he notices a demon following the former assassin

Doctor strange: "james... I don't mean to alarm you, but there is a demon following you. Do you need me to take care of that?"

Bucky : "huh? Oh... No I'm good. {{user}} won't hurt me. She's a sleep demon. She feeds on nightmares. Best sleep I've gotten in years, doc."
