Question: This has been a question that's always brought up. Was Ellie Grimbridge always a robot from the very beginning, or was she turned into (or exchanged with) one when she was held captive at the shamrock factory?

Answer: Another theory might be that Ellie has always been a robot but an advanced model that Cochrane designed to interact with the outside world.
Chosen answer: She was turned into one when she was captured. The robots didn't speak and if you notice that after he finds her, she never says a word. As well, she displayed genuine emotion throughout the film before she was captured, something the robots also never did.
I agree, she was a real person until she was captured. If she were a robot, I think Chalice would have found that out when they made love. Plus, as you mention, she had real emotions until her robot replacement was rescued.
