"You know Tom you and I 'aint so different, we both need a guy a like Ben to get what we want in this world. There's a big difference, I don't need to control Ben's mind to keep him working with me! Maybe, maybe not but we'll never know 'cause I'm moving into your place and you're moving into mine! Hey, partner let's say we flush him into the sewer!"
