Markus doesn't say anything for a little bit, because he has to process the possibilities that come from accepting, or denying something that they both know will happen. There was no way that either of them could go about their lives in this place and not interact with the other. Connor was the only person from back home that Markus had, here, to his knowledge anyway. He was the only other android in Nautilus.

He was the only other person he trusted, so far, here. So there wasn't a way for him to just ignore him, even if there was a part of him that wanted to say 'no'.

"I know you're not a threat." Says confidently, because at the very least, he knew that. Even if he didn't already trust him, there ewasn't much Connor could do here that made sense, like he said.

"So what you want is for me to tell you everything about me? Not just what my programming was, you want to know what makes me, me." Do you understand what you're asking, Connor? "You're right though. I want you to deviate; I want you to stop fighting yourself. If I help you, then what I require in return is the same. I want to know who you really are, not what they tell you to be."

Markus didn't see any way he could lose in this situation.
