I think this video does a good job of demonstrating several phases of a fight from the initial processing of what is happening, to the eventual decision to engage quickly and decisively. A great example of her processing what is happening and then in a split second she takes decisive and violent action. Her actions overwhelm her opponent and he ends up in the fetal position and his "plan" was foiled. It is not until his buddy arrives again that the situation changes again.
Agree, but the video was staged.
