A few questions I'd like your opinions on:

1. What do you think is up with Walt? Is he dead, kidnapped, or maybe he's off the island already?

2. Who's going to be next to die?

3. Is Charlie going to start using again soon?

4. What about Sun (SPOILER)'s pregnancy? Do you think it's really Jin's? If not, then what's your theory? Use tags, some folks haven't seen this weeks episode!!!

5. That guy in the locked room, is he one of the 'Others'?

Apologies if I spoiled any episodes you haven't seen yet.
