Claire mentions that her Dad used to sing “catch a falling star, and put it in your pocket” to her when she was little, of course we now know that Claire’s Father is also Jack’s Father.
Rousseau and the Others
Episode nine introduces so many important things, Rousseau, the underwater cable, Ethan, the whispers, and the first mention of “the others”.
Nadia
Sayid says that Nadia is dead, however we see her in other people’s flashbacks (Locke’s and Charlie’s I think) later on, so did she die after those flashbacks happened or is she not dead at all and Sayid just believes that she is. After all he says he is still looking, hoping that one day he will find her.
