"You actually thought i cared about you?"
"I wonder how loudly i can make you scream in agony?"
"It would be a shame if i had to damage that pretty face of yours."
"How could you do this to me!?"
"Is that supposed to scare me?"
"You look so sexy when you're all bloodied and bruised like that~"
"I wonder how many volts it would take to kill you?"
"Why are you pointing that gun at me?"
"You're so cute when you struggle like that~"
"Your blood smells wonderful."
"I thought you were dead!"
"What did they do to you?"
"Maybe i should carve a pretty picture in your flesh?"
"Don't worry, I won't do anything fatal, I just need some information."
"I don't care what you do to me, I'll never tell you!"
"Stop it, your hurting me!"
"The only reason I chained you up is to show you how much I love you!"
"If you keep struggling like that I'll have to punish you~"
