I'm all caught up. I just watched the Man in Black and Jacob episode that explains the origin of The Monster.
The second last episode will air Tuesday night. It's called "What They Died For". The 2.5 hour series finale airs next Sunday. It's aptly titled "The End".
Here's a home brewed promo for next Sunday's Lost finale. It's airing at 9, so I'm thinking I should start it at 9:50 to finish close to real-time without ads. Note to self: avoid Twitter at 9 sharp to avoid spoilers.
I hope they don't fuck it up.
