David's anatomy and eating?

He'd might say : -Command Error; Does not compute. ;)

Who cares - Its a movie and damm good one at that.

Uh, I care, thanks. I just wanted to know because I'm curious.

Even an android would need some sort of energy replenishment over a two year journey. Just as humans break down food to provide energy, David would also reasonably have similar requirements. He's not built like the Terminator or Commander Data after all, so he probably wouldn't plug himself into a wall outlet. Previously both Bishop and Ash sat down at the dinner table with the crew, although they weren't shown eating.

According to Xenopedia, androids charge via traditional means (plug-in, for lack of a better term). My theory: He is eating a special substance. Not food, but rather some form of lubricant or coolant. If you notice clearly by his severed head on the neck, you can see the white, tapioca-like beads that he was seen eating prior. We see all damaged androids leak a similar substance in other Alien movies, as well. So either: - It's a substance vital to the machine's operation. Or - Pulling off his head ruptured the chamber food is stored in before it is catheter'd away. Either way, it was still a good learning opportunity for David*, to better behave like an actual human, and further pull him out from the uncanny valley. If its the first case, then it's a good way to kill two birds with one stone. If its the second, then it's still a good learning opportunity regardless. Possibly, it might also be him checking the freshness of the ship's food stock. *It seems like the androids are not traditionally programmed, per se, but rather are raised and learn through experience, like the HAL 9000 series in 2001: ASO.

The real question is: What is Michael Fassbender eating because it looks damn delicious. I hope it's coconut tapioca pudding because it's mouthsex: http://thaifood.about.com/od/thaidesserts/r/thaitapioca.htm You can add corn, banana, milk (to eat within 2 days), beans, berries... Yummy yum yum zl'pzl'pzl'p!
