S17 - Able Katara

He turned his attention to Katara, who desperately attempted to deal Sokka's wound. Toph wanted to tell her to stop, that it was a lost cause, that he was nearly decapitated, but the words just couldn't come out, Katara trembled, sobbing, but their enemy was so close.

"Katara!" said Toph.
