So, a few episodes ago, I had an epiphany... I never come up with LOST theories, so I was pretty excited. So, you know Daniel Fariday- our physicist?
Okay, so remember a couple of episodes....when the island flashed back in time to the H bomb days? Remember the woman with the blonde braids that held Daniel at gunpoint and walked him out to the bomb to dismantle it? I think THAT is his mom (Eloise Hawking) and that Charles Widmore (remember...the young Charles Widmore was on the island at that time...) is Daniel's father. Thus, Penny is Daniel's half-sister.
Tonight, we went over to Brooke & Freeland's for supper and talked about LOST for twenty minutes and I tested out my theory on those two...I got a good response- they thought it was quite possible & even made sense.
