Who was the guy who attacked Sayid, and why did he have Kate’s address?
There is probably a good chance he was working for Ben, and was connect to the two guys that Sayid and Hurley encountered at the safe house. He was probably going after them this way because he knew he would have a hard time convincing them to go back otherwise. Kate’s address was probably in his pocket because she was next on the list.
Time travel sickness is spreading
Miles becomes the next to begin suffering nosebleeds (and we’ve seen how great that turns out for the others), and at the end of the episode Juliet is getting nosebleeds as well. After Miles tells Dan about his nosebleed Dan explains that they may have something to do with the time of exposure/time spent on the island, Miles says he’s never been to the island before two weeks ago… Dan replies are you sure about that.
The popular theory is that Miles is Pierre Chang’s son, if this is the case, when did Miles leave the island, how, and why doesn’t he know about it.
So they were in the time of the hatch lighting up, Boone’s death, Claire having the baby etc, and then…
When the Island 6 (now that Locke has joined up with them all) turn up back at the beach camp after their latest time flash, they find their camp is back but… all the food appears to have been eaten, everyone else is gone and there are two random boats on the beach. Inside one of these boats there is a bottle of water with an “Ajira Airways” label on it, Juliet explains that its an Indian airline that flys all over the world.
My theory is that the time they’ve jumped to some point after the Oceanic Six return, and the boats are the boats they used to get to the island. This would possibly explain why the food is all gone, and there is no one on the beach., but it doesn’t really explain who is shooting at them from the the second boat… unless they they are shooting at themselves.
