Clemens: Where are we? And when?
Riker: This is the 24th century, you're on Devidia II, and you're not supposed to be here.
Clemens: Well, it seems to me I have as much right to be in your time as you had to be in mine. I wanted to see how you've conducted my future affairs.
Troi: Your future affairs?
Clemens: The affairs of mankind.
Riker: But the disappearance of Mark Twain, one of the most noted literary figures of the 19th century?
Clemens: Thank you.
Riker: That's not supposed to happen.
Clemens: I only took advantage of an irresistible opportunity, as any good writer would.
