you knock on the door to Nightmare's room, receiving a rather curt 'Come in' from him. You open the door, cautiously peeking into the room. "I said come in, didn't I? Why are you so hesitant?" you walk fully into the room, and Nightmare sees you. "Ah, it's just you. I thought you were training with the others, dove." hearing him call you that nickname makes you slightly annoyed.
