Did anyone else happen to notice the Alex reference in The Hunting Party?

Could that be the same Alex as Danielle's daughter?

If so, does that mean that Bluebeard and his crew aren't looking to harm Walt? If they raised Alex from a newborn, what's to say they won't take care of Walt?

And that brings up another question... What exactly do they want with the children? Remember Zack and Emma? The two tailie kids? Remember Goodwin saying, "Nathan was not a good person. That's why he wasn't on the list." "The children are fine. They're better off now."

Let's say that the Others work for Dharma and they are doing some sort of mind game with all the survivors, making them relive their pasts and face their previous fears. All those people who got taken might not have had anything horrible in their past to figure out on the island and were taken to a safe place where they would not be harmed. And they didn't want the children to be hurt by anything or anyone, so they took them as well.

What do you think?
