A Lost spoilers rumor is that indeed we find the Lostaways rescue or a portion of it in Season 4, but it is not the freighter people who are the rescuers. We'll see.
Here is a Lost spoilers preview from ABC. An ominous tone is set with with Hurley saying "We're all gonna die" and creepy Ben saying, "Welcome to the war".
Here is the usual ABC Lost Spoilers leak for the episode, and as usual this may contain misdirection in addition to spoilers hints:
LOCKE’S CAMP COMES UNDER ATTACK, AND JACK ATTEMPTS TO IDENTIFY A BODY THAT WASHES ASHORE, ON ABC’S “LOST”
Who could that be? Think undersea explosion or dead freighter food.
“Lost” Moves to its New 10:00 p.m., ET Time-slot, Thursday, April 24
A lot more people time-shifting with tape, TIVO and ABC.com streaming.
“The Shape of Things to Come” –
Title Lost Spoilers not.
Locke's camp comes under attack, and Jack tries to discover the identity of a body that has washed ashore, on “Lost,” THURSDAY, APRIL 24 (10:01-11:00 p.m., ET) on the ABC Television Network.
Is it the Others or the freighter people?
