In a story I have yet to write in which time is a spacial dimension allowing those who are freed from the flow of it to walk it as easily as we can walk left, right, forward and back but, human beings being ill adapted to four spacial dimensions, nearly impossible to navigate or understand without the bunches of technology travelers use to make sense of what's before them, the veteran traveler gives his apprentice a weapon he tells him never to use. I think it may have been one of the scenes that I thought out first:
"This is an EMP grenade. Never use it."
"Why give it to me if I'm not supposed to use it?"
"There may come a time when things get so bad that you decide to ignore everything I ever said to you. It is possible that one day things will be so hopeless that you'll be ready to break every rule I ever gave you for even the smallest chance of survival. Hopefully that won't happen, but if that day should come ... well ... don't use it."
