LOST...you learn something every week

This week, we learned some new stuff:

Ben has been the one going after Aaron, so he could get Kate to leave the island.

The time flashes are starting to make everyone had nosebleeds and could provide further complications.

We know Jin is still alive and could be in the same time period as Sawyer and the others.

Who were the people shooting at them in the boat?

We meet Rousseau when she arrives on the island.

If Ben doesn't know where the island is, then how is he going to find it in the boat at the marina and how does he know for certain that Jin is alive?
