Oubliette

Mulder: Technically, but whether she knew it or not she 
        was repeating the exact same words spoken by 
        Amy's abductor at the exact same time 20 miles 
        across town.
Scully: Well, that's spooky.
Mulder: That's my name isn't it?

Scully: I hate to say this Mulder, but I think you just ran 
        out of creditability.

Mulder: You don't think I've thought of that? I have. And 
        not everything I do and say and think and feel goes 
        back to my sister! You of all people should realize 
        that sometimes motivations for behavior can be more 
        complex and mysterious than tracing them back to 
        one single childhood experience.

Scully: Did she tell you that?
Mulder: No. But I think that's what she's trying to do.
