Lost USA (Afleveringen amerika, spoilers!)

1. Des woke up and punched in the numbers 4-8-15-16-23-42 which add up to 108.

2. He then here the explosion from Locke Jack and Kate. The go back to the camp and Jack says there is 3 hours till dawn. Which meant that Des woke up in the middle of the night.

3. We know Jack came down the hatch less than three hours later because it was still dark. During that time Locke punched in the number and reset the countdown to 108:00 (less than three hours after Des reset it). It was at 002.23 (I think). 108:00 stand for only one of two options. Minutes (1 hour 48 minutes) or some other form of time not restricted to hour/min/sec. I think it was minutes which would fall into the time line from when Des reset it after he woke to when Locke set it (less than three hours) which rules out the 108 hour theory.

4. The timer has to be reset or it will self destruct. This does two things. A. it keeps Des from roaming around the island because he will have to go far. B. Prevents him from making contact with the quarantined area (the island) and becoming infected. Which by the way, I think, he takes the injections, to help prevent infection.

5. There was a ping pong table and two beds in the bunker. Letting us know that the bunker was made for at least two people. We assume Des is the only one in it and I think he is.

6. He has been in the bunker for who knows how many years waking up every 108 minutes to reset the timer. (I am sure someone will count up the tally marks on the wall and have some theories soon).

THIS IS WHERE IT GETS GOOD

7. Hurly found out about he numbers 4-8-15-16-23-42 from his friend in the insane asylum. The guy did not say much, just those numbers. He was once in the bunker, having to reset the countdown every 108 minutes for who knows how long and went insane. I don't know if he was in there with Des or not. Probably not, but that would explain the numbers and the guy being crazy.

8. Hurley’s friend also told hurly, when Hurly told him about the lottery, that he opened the box and he must get away from the numbers. Des referred to the computer as the box when he made Locke punch in the numbers.

9. When Des asked Locke "are you him?" he was looking for his replacement or something to balance the bunker again into two men shifts. That is why he was confused about Kate, He was only expecting one person.

10. Des was surprised to hear that they (43) people has been on the island for 44 days. This is because he would not expect anyone to live that long without being infected with whatever it is that makes people sick.

11. Des also says something like the "the world still exists?". That is because he not only thought that the infection was on the island, but thought that it would, by now, spread to the entire world.

When Kate walks into the recruiting station to talk with her step-father, whom she has believed to be her real father, on the TV in the background you can see Sayid being escorted by American soldiers

In the scene with Sawyer, Kate and the Black horse, the horse's Trainer's hand can be seen on camera on the right side of the screen.

The episode's title alludes to the 23rd Psalm found in the Old Testament of the Bible. It describes depending on God through the struggle with death. In a direct reference to Eko, it mentions a "rod" and "staff" which provides comfort; Eko's staff has been his constant companion on the island.

"The Lord is my Shepherd; I shall not want...
Yea, though I walk through the valley of the shadow of death,
...I will fear no evil: For thou art with me;
...Thy rod and thy staff, they comfort me."

We finally get to see more of the monster, revealed to be a swirling column of black smoke. Inside, there seems to be an elecromagnetic storm. When you pay closer attention, you can see that within the flashes of light, pictures of people, possibly from the islands past, can be seen.
