Dressed in her waterbending robes with her pouch of water slung across her chest and hanging at her side, Katara was, indeed, ready to make a difference. It was quite obvious into which area she fell. She definitely wasn't the magical type and had, in fact, never even heard about magic before her arrival in L.A. So clearly she was going to be helping to defend the premises. Which was just fine with her.
Listening as Angel spoke, the young woman let her attention sweep across everyone else present. There were a lot of them, a lot more than there had been when Zuko had first brought her here. Maybe, just maybe, there were enough of them to really stand a chance against whatever odds they were about to face.
If not, though, Katara knew she'd go down fighting. She simply didn't know any other way. And with that final thought and Angel's last words, she headed toward Wesley so she could receive her orders on where, exactly, she would be able to best help keep the hotel safe while those with magic brought back the sun.
