"I solemnly swear that I am up to no good."

"You can exist without your soul, you know, as long as your brain and heart are still working. But you’ll have no sense of self anymore, no memory, no . . . anything. There’s no chance at all of recovery. You’ll just — exist. As an empty shell. And your soul is gone forever . . . lost."
