K Changes The Future?

Karyn figured that her wish was too vague, because what they saw was an Indian settlement. Jon and Karyn exchanged glances and looked back at K. "What?" "How do you know that **you're** not the one that changes the future," Jon said. "What you mean?" "You brought that rifle back in time with you. What if one of those Indians got a hold of it?" "I never thought of that. But, your Karyn was the one that made the wish to come here." "Yes, but only because **you** told us about what might happen in the future." "Then, what do we do?" asked Karyn.
