First let me say, hahahaha.
If they had aired this I think people would be even MORE pissed at certain points during the run of this amazing show. Good thing its totally fake and shot after the fact*.
**Already canceled show Spoiler Alert**
-We find out that the smoke monster/Dark energy character's name is Barry (something he doesn't seem thrilled with)
-Everything WAS planned from the beginning
-Locke might know more than he was given credit for
-Jack is cranky (we already knew that though)
-"That Scottish Guy"'s job may or may not matter
-Metaphors annoy Barry as much as me during season 3
*but feel free to make your own call
