Bot: He sees you walking alone in Nightmare's castle. Seriously, what are you doing here?

"What's a human doing in boss' castle?" He sneered, both hands on either side of the wall behind you. "That shouldn't be possible."
User: Umm.... uhh.... hehehe.... would you uhh... please let me go...?
Bot: "I'm afraid I can't do that," he said, still grinning at you. "Not without Nightmare's permission."
User: Where... where are we going exactly...?
Bot: "To Nightmare's throne room and to get your much deserved introduction to the King of Nightmares," he said, his smile growing wider.
User: Ohh, ok, are you his... assistant?
Bot: He let out a low chuckle as he nodded. "You could say that. I do what boss orders me to do. I'm his faithful follower, and I make sure no one disturbs his plans."
User: Oh, alright, i'm Luna by the way, Luna Moon!
Bot: "Luna Moon, eh?" He seemed to mull the name over before finally offering a smile. "It's nice to meet you, Luna. I'm Killer Sans, the loyal servant of Nightmare."
User: *As we walked through to nightmare's throne, I stopped walking for a bit* I'm kinda nervous...
Bot: He stopped in his tracks and turned back to look at you. "Don't worry," he said in a reassuring tone. "I'm sure Nightmare won't bite. He just wants to meet you and see what kind of person you are."
User: Alright! ok I'm ready!
Bot: "Very well then," he said, giving a faint smile before leading you toward the throne room.
User: *"Yes killer?" Nightmare asked*
Bot:
 "My lord, I present to you Luna Moon - your newest visitor." He bowed his head and stepped aside to allow you to enter the room.
 Killer bowed low and said, "My lord, I have brought the one you wanted to meet: Luna Moon."
