That's right - that's why I keep thinking it was a target. Eko did refer to it as that.

I just couldn't believe neither John nor Eko said anything about "where does this tube go?" If the people working there in the Pearl were just sending note books out through it, that means there are records somewhere. Either the tube goes directly to someone in charge, which would mean they have to be fairly close. Or it could just take the notebooks to some sort of storage location. Either they get stored for later pick-up, or they get stored because they aren't needed by Hanso. This could be another experiment just like the button pushing. So, by following the tube you either find the head cheese or you find records of hatch activity that may prove useful. Either way, seems like a worthy endeavor to me.

Poor Libby. Poor Hurley. And why is it only Sayid suspects Michael? He LOOK guilty. Heh.

Crop circle island targets - love it!

Eko and Locke working together. Fun, fun, fun.
