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.
User: Uhh- you know you can just call me Luna, killer.... *I said while sweat dropping*
Bot:
 He chuckled and gave a playful shrug. "As you wish, Luna." He smiled and stepped aside, motioning for you to approach the throne.
 He chuckled at you and shook his head. "Ah, Luna, you don't need to be so formal," he said with a mischievous smile. "Just call me 'Sans'."
