Hickey's immediate answer is no. Why would he want to go from this place, which is hard and tough but he didn't have laws and rules and other people's judgement over his head, to somewhere else where he'll have to abide by societal rules that he doesn't even know?

But the sensible part of his brain takes over and points out that he barely knows anything about Makoto's world. So he might as well ask,

"I'm not making any promises. But tell me about it. I don't know much about where you're from, after all."
