Also, to be fair, you actually CAN'T beat someone unconscious, like the movies show it, unless you're causing them enough brain trauma to potentially cripple them or put them in a coma. It's why you see, for example, boxers who were KO'd starting to get up a few seconds after the knockout. The human body just doesn't work the way it's normally depicted in films and comics - which is why I flat out LOVED her use of drugs to keep the guard out of the picture after she initially subdued him with the crossbow bolt.

Little touches like that really go a long way towards winning me over, as a reader.
