...on tonight's episode "The Package"
1) Assuming it's a Jin/Sun episode (which it kinda looked like from last week's preview), we're going to see lots of people popping up in their Alt story. Sayid and Keamy for sure, but I'm betting we'll see both the MiB and Desmond too (remember him)
2) "The Package" will refer to whatever Widmore has in that locked room
3) We'll finally learn how Jacob's replacement is chosen (holdover from last week)
4) Smokey will offer not to kill everyone if Frank flies him off the Island
5) Ben will finally explain to someone how the "Magic Box" works
6) Hurley will set up a ping-pong tournament with all the ghosts on the Island and win by default when they can't pick up a paddle.
I'm 100% certain all these things shall come to pass.
Enjoy the episode! Review up tomorrow morning! :)
