Daniel Faraday is Charles Widmore and Eloise Hawking's son

As Eloise Hawking is leaving the Marina Medical Center in Long Beach, Charles Widmore is waiting for her outside. Widmore asks her if Desmond is alright and she says that he's fine. Eloise tells him that Penny is inside and that he should go inside and say hello. Widmore says that his relationship with is daughter was one of the things he had to sacrifice. Eloise gets angry and says "Don' you talk to me about sacrifice Charles. I had to send my son back to the island knowing full well that..." Widmore interrupts and says "He was my son, too, Eloise." Eloise slaps him across the face then turns around and gets in a cab.

So it was a little surprising, but not monumental that Daniel is Charles Widmore's son. It was not as obvoius as the Pierre Chang and Miles relationship. Charles widmore uses the word "was" when referring to Daniel being his son, so he seems to know that he died in 1977.

Eloise Hawking apologizes to Penny, Desmond is in recovery

We go back where we started at the beginning of "The Variable" which is the Marina Medical Center in Long Beach. Penny is stunned to find out that Eloise Hawking's son is Daniel Faraday. Eloise says to Penny "I came, Penelope, to apologize. Your husband has become a casualty in a conflict that's bigger than him, that's bigger than any of us." Penny asks if Desmond is going to be okay and Eloise says that she doesn't know. She then says "For the first time in a long time, I don't know what's going to happen next."

At that moment a couple of nurses come in and one says that Desmond is in recover and is asking for Penny. The nurse says that Desmond is going to be okay and that the other nurse will watch Charlie. Eloise leaves the room after Penny does.

Penny goes into Desmond's room and says "I though I'd lost you." Desmond says "I promised you, Penny. I promised you... I'd never leave you again." Then there is another dramatic Desmond and Penny kiss.

So why is it that Eloise Hawking's ability to see the future is not working right now? Does this have something to do with the impending war that Widmore referred to in "The Life and Death of Jeremy Bentham?"

Also, does anybody else think that it might have been a bad idea to leave young Charlie with a stranger, even if she is a nurse?
