““Just tell me before you go," said Lee, "because I won't be easy till I know. What side I'm fighting for I cain't tell, and I don't greatly care. Just tell me this: what I'm a-going to do now, is that going to help that little girl Lyra, or harm her?" "It's going to help her," said Grumman. "And your oath. You won't forget what you swore to me?" "I won't forget." "Because, Dr Grumman, or John Parry, or whatever name you take up in whatever world you end in, you be aware of this. I love that little child like a daughter. If I'd had a child of my own, I couldn't love her more. And if you break the oath, whatever remains of me will pursue whatever remains of you, and you'll spend the rest of eternity wishing you never existed. That's how important that oath is.””
