Lost Episode 2.01 Man of Science, Man of Faith

A man is roused from sleep by his alarm. He jumps out of bed, types briefly on a computer and presses the "execute" button. He puts on a record (Mama Cass) and cleans up last night's dishes. He does his workout, takes a shower, makes a protein shake and gives himself am injection of well, something. And then BOOM! We hear the explosion and follow the man's frantic reaction into a gun locker where he loads up with pistols and a rifle and then goes to a primitive type of periscope he uses to discover the cause of this emergency. There, at the top of a very deep shaft, are Locke and Jack who've just blown the hatch. Welcome back to Lost everyone

Seeing the depth of the shaft, Jack manages to get everyone to return to camp with him, leaving the exploration of the hatch for another time. After all, the reason they blew it open was to hide everyone inside and that's not going to be possible. Upon his return, Jack even manages to calm the rest of the survivors down and convince them that, regardless of what they may have heard, they will ALL survive to see the next day, as long as they all stick together. But Locke can't wait any longer and openly defies Jack's orders by returning to the hatch that night. And just as Jack thinks that one person defying him was bad enough, Kate decides that she's going out there too.

Meanwhile, Shannon is frantic after losing Walt's dog Vincent. Sayid tries to convince her not to go out into the jungle looking for him tonight, but she will not be swayed. Finally, someone has trusted her enough to ask her to care for what they loved most and she's lost it. Not acceptable! So together they venture out into the dark and Shannon has an eerie encounter with Walt himself. He can't really be there, can he? He's out on the raft! But there he is, dripping wet and looking terrified. Before Sayid joins her, Walt disappears and she is left to wonder if she ever really saw him at all.

In FLASHBACK, we see Jack in full hero mode as he works on a patient brought to his emergency room after a terrible car crash. Her name is Sarah and she tells Jack one thing before she passes out. He has to fix her because she MUST dance at her wedding in a few months. And we see the very moment that Jack met the woman who will eventually become his wife. While Jack takes a late night run, trying to accept that even his skills have their limits, he meets a man as driven as he is. Turns out "Desmond" was going to be a doctor, too, but gave it up for something else everything else. Desmond realized there was more to life than what you could learn in medical school and he tells Jack that sometimes miracles can happen if you just believe. Jack thinks him a total crackpot, but is forced to reconsider when, against all odds, Sarah regains feeling in her legs.

Back on the island, Jack decides to follow Locke and Kate down the hatch. As he makes his way through the bizarre surroundings, that same Mama Cass song starts up again and Jack suddenly finds himself in the middle of a stand off. When the man holding a gun to Locke's head steps further into the light Jack gets the shock of his life. That guy threatening to blow Locke's head off? It's Desmond. The same guy Jack met running that night in another life.
