With all the stuff thats been revealed to us in the last few eppisodes, this is something that seems to be, well...off.
The children with the Others....are 815'ers
The youngest known Other...is Alex who presumably was that last birth on the island.
No women ON the island can get pregnant.
It's a stretch to think "Jacob" would "recruit" a child...ala Patchy/Juliet
Alex doesn't look 16 either. I think we're just supposed to take their word for it. However, I am still not sure that Danielle's message has been playing for 16 years. I think Sayid got his math wrong.
But Danielle herself claims at any given chance (eg, Greatest Hits epi)that her messages been on a loop for the last 16 years!the question is not whether she thinks its 16 or more as it doesnt matter what both Sayid or Danielle think!time goes by differently on the island!we can be sure of that by now!maybe Carl didnt spend all his life there!hence his older looks
Yes, Karl was the one who took the X Rays. What makes me wonder about him was why was he in the cage next to Sawyer's? Was it just to keep him away from Alex, or was there something more sinister going on?
I just find it non-linear, or very TV-like that all the clothes remain in pretty much perfect shape.
Also after 3 months worth of growth I'd look like Kingsley Holgate, yet these people's hair never gets longer, they retain that 3day old beard look, etc. http://www.ports.co.za/images/kingsley-holgate-001.jpg
