Let me get this straight, in the sideways, Sayid made a clear point that he doesn't deserve to be with Nadia because of his malevolence past.
Yet in the original time, Sayid was with Nadia off the island for quite sometime, he didn't even think about his deservingness to be with Nadia. Sayid still has the malevolence past. After Nadia was runned over, Sayid plead to MiB into bringing back the woman he loved that died in his arms (Shannon). Does that make sense at all? Was Sayid with Nadia but thinking about Shannon hot island sex?
