Aw I just love Desmond and Penny! What a great episode! I know it's probably not answered that many questions like Richard's episode did but it was still great!
So memories from the original timeline are bleeding into the alternate timeline now for Charlie, Desmond and Daniel. So who will be next? Love it!
Oh and just to clarify, Charlie was talking about Claire in his memory wasn't he? Or did I miss something? Would he not have recognised her as a girl on his flight?
