Most Alleys, because of their battling style, waiting until all opponents had attacked to go again, but it was two against one and she knew she couldn't win if she waited. Ada jumped up and pushed Foxx down, raking at her belly and leaving a well-sized gash. She jumped back to avoid being hit again, but stumbled. She picked herself up, but her fall could be used as an advantage.
(Remember, during fighting, Alleys can't be perfect. They'll have to be at least hurt a bit, and they can't dodge every attack and/or get every move right. Just a reminder, not like I am accusing anyone..)
