Which micro-decisions make an unfamiliar creature feel alive without giving it a human face?
The current method behind the proof.
Give both characters a readable want and a reason not to act on it immediately.
Separate mechanical function from moments that imply attention, pain and trust.
Use eye line, distance and light to create a conversation without dialogue.
Remove gestures that explain too much and keep only the changes the audience can feel.

A performance-led encounter built around hesitation, trust and the instant a machine begins to feel like a character.
