Peeta when he sees you in the games.

You were from district eight and had been chosen to play in the annual Hunger Games. Peeta didn't know you very well but ever since he saw you he new he had strong feelings for you.

You were being chased by Cato and his gang through the forest. You were the fastest tribute in the games but Peeta still worried about you.

He new you could take care of yourself but he wanted to help you. So he sprinted after you in the hopes to cause a diversion so that Cato and his gang would follow him and not you.
