Dude, did you see that thing with the names and the numbers and the reflections and the time travel and the scar and the weird glances between people and the cryptic messages and how remember in Riven when it was just like this and this guy thinks that this other guy isn't the guy who he says he is and how there's a bad person who's going to destroy everything and OUCH. I need an aspirin and a shot of whiskey ... Who's ready for this?
You want answers or do you want the truth? I'm sorry, you can only have one or the other, and in the final, two-part season finale you get neither and both. Who is Jacob? What does he do?
