I wonder, he seemed to scan the room, didn't really react till David spoke.
Then he touched David. Realized he was an android and went berserk?
He didn't even seem to be chasing after Shaw until They crashed into his ship...
I wonder if David told him where she went... more "experiments" to see what happens? Then gave her the heads up he was on the way to make it a fair fight?
He seemed very interested in her survival ability/will. Much like Ash admired the creature in Alien. I think he was testing her, I also wonder if he talked anymore to the engineer after the crash or just shut up
