"Aren't you a little too young for Neverending Story?" he asked with his own little smile. "I don't think my people your age even know what that is, let alone name the characters."

He understood long before you- we did. He spoke with Hetty long ago. He was very adamant about the consequences. It's why we went with his recommendation. I know that caused a problem between you two, but he had something that you didn't have yet. Experience with people. You've grown plenty in these two years."
He lifted his head and stared at John. "A failsafe is fine, but nothing linked to a specific person. Too much can go wrong. Even failsafe must have failsaves. If something were to happen to one of us, then it would all fall apart."
