You're like a little worm on a big ****in hook, man. Here's what happened...
Mac and her fought. She beat him to the ground, looked at his STILL, NON MOVING form and assumed he was down for good, then, yes, she went back to Farrell to make him undo what he had did.
Then, Mac got up, beat her to the ground, then walked back to Farrell (same as she did in fact) to tell him to carry on what he was doing. She got up and BFR'd his ass.
Doesn't matter if she was down longer, she held the upper hand at the end of the H2H battle. It was only because of an SUV that Mac was able to win. Hell, even then he had help from gravity and Farrell.
To say that she saw him moving while on the ground is just plain silly. If she had seen him moving, she would have bent down and snapped his neck.
