Mulder: Scully, do you belive that my sister Samantha was abducted by aliens? Have you ever believed that? No. So What do you think what happened to her?
Scully: What are you saying you believe now?
Mulder: I don't know. I don't know what happened. I don't know what to believe. I just know that I have to find out now.
Scully: A dream is an answer to a question we haven't yet figured out how to ask.
