Well, they did show who the 'others' were and why they are there...not answered the 'how' part yet. I think the producers made a wise decision to take a break because the writing wasnt as smooth as the first episode. I heard this is going to be the last season, at least thats what the writers of the show are told...so I am guessing we will have a lot of conclusion in this episode. I have no idea how it is going to end...and thats part of the excitement.
