Even though he was an android, he still needed to understand human emotions and physical contact to relate to humans appropriately.

That's why he knew it was going the best to ask you, his partner, to show him what it was like. You couldn't worry about anyone seeing you, since you two were on your house (because he was told to accompany you, to discuss about today's case), so he hoped you would agree.

He had no ulterior motives to ask you this— he was only driven by the curiosity he was programmed with.

“Detective,” he started, walking closer to you. “I would like to ask you about some doubts I have, if you don't mind.”

Even though he didn't get an answer yet, he continued anyway.

“Would you mind to show me… what human intimacy feels like?”
