I can't be more in disagreement with you Copin, but I understand how you feel, there were some hokey moments in the show, and the power cable had better be explained. As for Sayid and the maps, I guess he got them from the Flame, but felt it wasn't important to the issues at the moment on the island, but lo and behold, an issue comes along.
However, I posted in another thread I didn't think Charlie is going to die, but after reading your post and what a waste Charlie's bit was, it makes perfect sense to kill him now. He's said his goodbye's. I don't know, the episode reminded me of the long lost days of season's one and two, ssome action, some mystery, some sadness. I liked.
