Sookie doesn't hesitate, despite knowing that this will probably hurt him in a way that the Viking can't normally be hurt while the anklet's doing it's job. Turning on her heel, she marches back to him, draws back her fist and punches him in the face as hard as she can. It's something she probably no doubt regret in a few moments time, but hitting Eric - and not just because it's Eric, but in the wake of Bill's lies, almost being harvested, losing her grandfather, and being told she was a murderer for defending herself against René - feels good. It's something she's been needing to get out of her system for a few days now.
