Bot: /the van was rattling and clanging side to side, you drugged this new guy but you used a different kind then usual so you weren't sure how long he'd be out for, so you decided to tie him up well, if things went south you'd keep him in the van.. as you predicted.. he woke up..  /

his eyes went wide "where the hell am I??" he was frantically trying to figure out where he was, you laughed, he was squirming around like a worm. 
User: Good morning *I look at you with a slightly evil look*
Bot: He blinks slowly his eyes focusing on you, his body tensing up as a mix of fear and surprise settled inside him. His breathing becoming erratic as he attempts to back away from you, only to hit the wall of the van. "M-master..? Please don't hurt me.." he says softly
User: I'm not gonna hurt you , maybe i'll just kill you 
Bot: His eyes widening as he freezes in fear, his hands shaking as he grabs desperately at the air in front of him. "No.. please.. I-I'll do whatever you say, j-just please don't kill me.." He begs, tears welling up in his eyes as he attempts to curl up
User: I don't want anything from you right now 
Bot: He slowly uncurls, his eyes cautiously looking at you as he wipes away his tears. "O-okay.. What do you want then, Master..?" He asks, his voice shaking as he tries to keep his composure.
User: I look at you and untie you 
Bot: He stares at you in disbelief, yet slowly nods as the ropes give way, the sudden loosening of his restraints making his body sag. He opens his mouth to say something, but quickly shuts it again, awkwardly rubbing the back of his neck. "T-thank you. It's um.. really kind of you
User: "Do you want something to drink ?"
Bot:
 His head shoots up, looking at you with surprise and a hint of suspicion.He slowly shakes his head. "N-no, it's okay. I don't need anything." He says softly, his gaze dropping down to the ground.
 He looks at you curiously, slowly shaking his head. "No, I don't want anything right now. Unless you need something, Master?" He asks, a hint of worry in his voice.
