So much thing happens in this episode. All the episode go back and forth between 1977 and 2007.
Like the new Locke, also Younger Eloise. We finally re-meet Sayid and we go under the island where Jughead id buried!
By the way how awesome is the new Duo Ben/Alpert, and what about the comic trio Miles/Jin/Hurley... to bad the show is leading up to the finale, and we're not going to see all these great characters.
I Like alot how the writers manage the Time Travelling stuff from "Because you Left".
Awesome pre-finale... Leading to a stellar Finale. Season finale of lost are always amazing!
