I remember when I first got into Chelley last year
I had this idea where Chell became some sort of Robotics expert and they were making prototypes for a voice substitute. So she can talk, and that was sort of her main focus.
Then she found Wheatley in a dumpster and brought him back to her lab, where she got someone to put him in a prototype android body. Then he learned some stuff and things.
There was a scene where they went out and were in the park. She touched his face, but got sad.
Sad because he wished he could feel the warmth of her hand.
but he couldn’t
because he had no nerve endings
