Jack:Morning.
Kate: Morning yourself. I bought you a razor.
Jack: What, you don't like the scruff?
Kate: (Laughs) Razor's by the sink, Jack.
(Shower shuts off)
Jack: Morning.
(They kiss)

Kate: It's just... it's just sweet hearing you say nice things about your dad.

(Kate is walking Jack to the stretcher)
Kate: So, it looks like I'm gonna be your nurse.
Jack: Wouldn't be the first time. (Kate smiles remembering) Listen, ahm, if something happens to me...
Kate: Shut up, Jack.
Jack: (smiles) Fair enough.

Juliet: (To Kate) You know he kissed me.
Kate: What?
Juliet: The other day, when you came back from the other side of the island, Jack kissed me. It was nice. But it wasn't for me, it was for him. I'm pretty sure he was trying to prove something.
Kate: Prove what?
Juliet: That he doesn't love someone else.
Kate: Thank you, Juliet. Thank you for saving his life. (She leaves)
Juliet: (To Jack) I know you're awake.

In the forum, some people were referring to him as a ghost? What the hell is happening? Is he dead or alive?
