Quote from : X-Men: Days of Future Past Movie

Logan: If you had your powers you'd know I was telling the truth.
Charles Xavier: How do you know I don't have...
[pause]
Charles Xavier: Who are you?
Logan: I told you.
Charles Xavier: Are you CIA?
Logan: No.
Charles Xavier: Have you been watching me?
Logan: I know you, Charles. We've been friends for years. I know your powers came when you were nine. I know you thought you were going crazy when it started; all the... voices in your head, and it wasn't until you were 12 that you realized the voices were in everyone else's head. Do you want me to go on?
Charles Xavier: I never told anyone that.
Logan: Not yet, no, but... you will.
Charles Xavier: All right, you've piqued my interest. What do you want?
Logan: We have to stop Raven. I need your help. We need your help.
Charles Xavier: [emotional] I think I'd like to wake up now...
[walks away]
Hank McCoy: [to Logan] What does she have to do with this?
