“After the anthem, the tributes file back into the Training Center lobby and onto the elevators. I make sure to veer into a car that does not contain Peeta. My elevator stops to deposit four tributes before I am alone and then find the doors opening on the twelfth floor. Peeta has only just stepped from his car when I slam my palms into his chest. He loses his balance and crashes into an ugly urn filled with fake flowers. The urn tips and shatters into hundreds of tiny pieces. Peeta lands in the shards, and blood immediately flows from his hands. ‘What was that for?” he says, aghast.”

In the book, Katniss went OFF on Peeta, making that man bleed.
