Katniss is right behind her, swift on her heels, Clove's blood still warm on the blade and on her cheek, but she doesn't care. Arya is here. She had to protect Arya.

She hears the breaking of branches in front of her and calls out, "Run, Arya! Run until you can't breath! I'm right behind you!"

She can hear the slaughter behind them, and knows it won't be long until they're coming for them too.
