Mr. Bester, we no longer have any ties to Earth or to the Psi Corps. So we don't have to put up with you or your games. Now, I am sitting on four brand-new unidirectional pulse cannons. Give me one good reason why I shouldn't blow you out of the sky!
Because you're curious? Kill me, and you'll never know what brought me all the way out here. I think if you weigh that against the brief satisfaction of "blowing me out of the sky", you'll do the right thing.
I suspect you'd rather walk out that door and wall me up inside! Do a little re-creation of "The Cask of Amontillado". "For the love of God, Montresor!"
