" Valkyrie walked over to her. Since she had met her, all she'd wanted to do was punch her face in. But that was when Kitana has been big and powerful and brimming with murderous arrogance. The girl standing before her now, crying and blubbing like any teenage girl would do under these circumstances, was not the same girl Valkyrie had wanted to punch.
But she'd do.
Valkyrie's fist connected with such a satisfying jolt that it actually made her smile as Kitana fell sideways, eyes already rolling in her head. Valkyrie resisted the urge to kick her as she lay crumpled.
Such behaviour would be unbecoming of a Sanctuary detective. "
