Seeker followed Jack to join Eve. The ultimate battle is coming. She could feel it in her bones. The wind outside picked up without warning, and the chill threatend to freeze her right down to her very soul.
She faced Eve, with such a loathing in her eyes, that if looks could kill, Eve'd be dead by now. "Lets just get this over with, shall we? There's no point in pretending anymore. We all know what your game plan is, and we're going to stop you, no matter what.
"But, before we do that, I want to give you one last chance. Hand over the antidote...the real antidote, and we'll divise a compromise. Else..." Seeker paused, then carried on in a much lower voice, "we'll just have to kill you."
At that point, Seeker knew she could, would do it. After all, she's not exactly a novice at killing. No matter how much it might hurt her later on, she's not afraid to do it. When the time comes, she'll be all to willing to nail the sword home.
