mrv3000 | I've figured out Lost.

Ben and Penny's dad (who does have a name, but I'm too lazy to look it up) are aliens.

Yup.

And they're on Earth, playing a long game where there are rules and the goal is to get off the planet first without using alien tech - only stuff made by Earthlings is allowed, hence the Island of scientists. (Also, killing people on a pre-defined list isn't allowed. And no killing each other.) The loser has to sniff the other's socks.

Or something.

P.S. If you kill Penny, I will be VERY CROSS.
