Every choice we make affects the world around us. Every decision creates a new set of pathways that we can choose to walk down. The future is just one massive branch of options. Is it fair to say then, that if Peeta hadn't seen Katniss on that fateful day with the bread, that Katniss' life would have taken a different turn and a new path would have appeared. Non-canon.

Peeta, a popular actor, lost his heart 5 years ago. Katniss, a mother, loves the children she gave birth to 5 years ago. Peeta meets 2 children who looks exactly like him and they were born 5 years ago. So what really happened 5 years ago? Two people know: Katniss, but not Peeta.
