Lost never seems to be short on plot twists that can shock even the most avid fan. The shocking reveals began early in the first season. Some of these shocks were things that some of us guessed before they actually happened, but even the thought of them happening was shocking, so I've listed them here.
5. Dad?
As Locke and Eko watch the Orientation film that says not to use the hatch computer for anything other than the code, Michael sits at the computer and types, "Hello?".
"Who is this?" shows up on the monitor. Michael types, "This is Michael. Who is this?" After a pause, on the monitor comes the word, "Dad?"
Episode 2x9, What Kate Did
4. Lockdown
In the hatch, a lockdown takes place as blast doors come down all around Locke. He lets Henry out of the armory to help him. Locke tries to crawl under one of the doors, but it comes down on his leg. He sends Henry to crawl through the vent to type the numbers into the computer. The lights go out and Locke sees a map on the blast door.
3. The Hatch Implodes
Locke won't let the code be entered and the timer gets down to zero, then there is a huge magnetized charge. Desmond goes below the hatch and turns the failsafe key. Locke, Charlie, Eko, and Desmond are inside the hatch. Everyone on the island hears a horrible noise and sees a bright light.
2. Portuguese Guys
After the hatch implodes, two Portuguese guys in a small room surrounded by snow, notice that it says Electromagnetic Anomaly Detected on the computer. One of them dials the phone. In a home, the phone rings and Penny Widmore picks up. The man says, "I think we found it."
1. Desmond in the Hatch
Season 2 opens with a man going about his morning routine. We soon learn that this man, Desmond, is on the island. He's what is inside the hatch. Almost as shocking is that he and Jack had met several years earlier when they were both running in a stadium.
