When Henry attacked Ana Lucia, he said she's kill two of them already. What two is he talking about? I know she killed Goodwin. Mr. Eko killed one with his stick. Ana shot Shannon, I recall. What other 'Other' did she kill?

The female one she killed with a rock, when they took the kids. Remember that was when they found the list of tallies they were going to take.

Also importantly, Ana mentionned Cindy... who alot of people though was just fired and would never be mentionned again. But she was, so good chance we will see her at some point again I think

When did Ana mention Cindy?

she asked michael if he saw cindy
