Also, I think Nathan Bateman is more touch starved than I realized. Sure, the robots have are practically human and soft but that probably doesn’t compare to actual human touch.
You can’t tell me that man would fall to his knees when some just cups his cheek. I noticed at one scene, he actually places Kyoko’s hand on his cheek.
This could be for many reason but to me this seems just like him acknowledging that just because she looks human doesn’t mean she is. Maybe he hasn’t perfected actual human touch because it can be so different. It’s not just a line of code.
This probably doesn’t even make sense but let me ramble
