So here's my big question about this episode:

Why didn't Locke and Jack and Sawyer try TALKING to the big hairy guy? If I was stuck on that island , and I finally had contact with the people who claimed that it's their island, their food, their computer, I think I'd be asking questions like crazy! Like:

Where are we?
Where did you come from?
What's with the computer? The numbers?
How do we get home???

I understand he's big and scary and everything, but if it were me, I think I'd at least try to get along with him. They might even get some answers about how to get home.
