Oh sorry but I will be fresh and say I love searching and finding the threads where discussions of topics that have been confirmed.
It is actually refreshing to look back at why we thought these things instead of opening up yet more threads of discussion. My humble opinion -rhetorical at best and perhaps a peeve that we don't take time to look back

So Mac three Mango Bingo had a good thought regarding parentange of Desmond and having Ellie as his Mom and unknown father. Which got me thinking of Desmond and his chance encounter of Penny and voila you had it here. Just a great thought, we could be on to something. It also has me thinking that the Monk and Ellie could be Desmond's parents

But the main purpose of my post is that I was discussing this last night with a friend and there is a deep connection with all three of the research team.
Charlotte was on the island - left with her Mom
Miles was on the island - left with his Mom
Daniel was on the island we believe- left with his Mom
All raised by their Mom's
I cannot say for fact that they were all born on the island, but let us for the sake of discussion say they were.
Miles has an ability to hear what the dead have to say
Daniel- well he has the book of the past
Charlotte - poor Charlotte not sure what she brought there other than a desire to find what she was told was a bad memory. Her Narnia so to speak.
But Widmore knew about these three and pursued them, so if for the sake, again of discussion, he knew of these people their where abouts off the island and sent them back did he also know what their fate was like Ellie?
The only person we do not know who the father is Charlotte
Now let me throw into the mix the other who doesn't know their father and that is John Locke.
BTW for all those calling Miles and Marvin father and son congratulations
And for those with connecting Widmore and Daniel also take a bow.
Connecting the dots is fun and even nicer when you are confirmed!
Anyway regarding our scientific team we can figure out who what when where, but still missing a why? What does Widmore know that he hasn't put on the table.
I know he wanted Danile healed, but for what means to his end?
