I see people bitching all over the internet about this. I think they're answering questions, but they're not beating you over the head with the answers. I thought last night's episode was brilliant.
Yeah i loved the episode aswell, i think it will come off even better when we see the two-hour finale.

another interesting thing, is this season overall will probably be much better paced and told via dvd, since theres alot of stuff that was cut in this part of the season, and i think the DVDs are going to include all the deleted scenes, it's also already confirmed that the finale will have a longer length on dvd.

One thing i forgot about, is most of the questions probably wont be answered untill the two hour 'the plan' movie' that's suppose to air a few months after the finale apparently.
