Bob smiles with just one corner of his mouth. He is amused by what Rosanne is asking.
"Negotiating already, huh? I've been on my job long enough to know how to not let anyone take advantage in a negotiation. I will only exchange anything unless what you tell me is truthful and helpful."
Rosanne laughs, "Jeesh, I'm not a criminal trying to work out a plea deal with the police. I just want to let you know I've got a glimpse of your secrets, too. So, don't be too cocky."
"OK. What do you want in return?" Bob tilts his head a little bit.
"I want you to tell me who you really are." Rosanne looks at Bob with her sea green eyes, which sends a tingling and nerve-racking sensation to his body. He feels nervous about his real identity for a second, but he immediately decides that Rosanne is bluffing. There's no way she would know. Just because she saw him having multiple ID cards doesn't mean she knows anything.
