LOST : The Dharma stations

In this most recent episode of Lost Mr. Echo and John Locke find station 5 the Pearl. I'm still having trouble seeing a connection between the station name and...well anything. Below of course is the swan insignia. Anybody remember what station that is? The Pearl was #5 out of 6 according to the video they watched, but John Locke's map showed 7 or 8 stations on the exterior of the octagon and one in te center. Was the Pearl the center one? The center one was the one marked by the question mark (see my prior blog entries for pics). If it is how can it be 5 out of 6 when the map showed more stations?

In addition, Mr. Echo had a flashback in his dream where images were flashing quickly by right before he appeared inside the Swan with his brother. When I slowed the images down this arrow station insignia was in it. It could be a compass too I guess given the fourfold breakup of the circle (four directions) and the arrow is pointing north just like the compass Sayid had on a 1st season episode. Was this from the station that we saw the tail section survivors in when they had taken Michael, Jin, & Sawyer prisoner. It had been lit by fire light I believe. If so that still leaves the station that Claire was in. Anybody remember what station that was? That makes four "we've" been in.

In addition, 2 weeks ago during the episode there was a bogus comercial for the Hanso foundation mixed in with the other real commercials. If you go to www.thehansofoundation.com it gives some interesting insight into what direction the Dharma project is going in. Check it out.
Another website which I believe is the one they gave on the commercial is www.hansorg.com It also is interesting. It has this quote hidden 3/4 of the way down the web page

A Nations birth predicts it's own demise and rebirth 2 10 13 18 21 44

This of course also equals 108 just like the first set of numbers. Interesting quote especially given the letters on that website. I just love a mystery!
