If we were to go beyond the idea of children just being captured, Hurley would also fit into this. The numbers have brought him bad luck, so he is cursed. But Hurley has also predicted the past and present not knowingly. I checked
TV.com for some quotes and I saw Hurley was quoted saying, "4, 8, 15, 16, 23, 42, 4, 8, we’re dead, 15, dude we're dead, 16, 23, 42." Notice how he said, "We're dead" after the 8 and then, "Dude we're dead" after the 15. Adam Rutherford was pronounced dead at 8:15 as a result of Sarah's car accident. Not sure if that's significant enough to be called a solid connection or just a coincidence, but I found it interesting nonetheless. However, we do keep seeing these numbers come up again and again. So this means Hurley does have some sort of powers with those numbers.
