Bryn ran to the border, which took awhile for her human body, and waited.
Callum showed up, just the wolf she was waiting for. At that moment, seeing him in wolf form, she knew that he was going to lung towards her and bite her. It was what she wanted before the whole war had begun. She needed it to become a true leader of her pack.
But something at the last moment, just before he made contact with her skin, made her rethink her options. She was doing this for her pack, to protect them, but there was other ways.
She whipped her knife out with enough time to steady herself, then plunged it into Callums heart just as his claws met her chest.
A high whimped pierced the air, a horrible sound that made Bryn want to die. Callum layed withering on the ground, a knife sticking out of his body, squirting blood everywhere. He flung himself around, desperatly trying to remove the weapon, but it was no use. His last resort was slowly changing back to a human and staring pleadingly at Bryn.
Bryn ignored him completely, but not without a tear falling down her cheek. She had just stabbed her only father. It would wruin her forever, but it was the right choice.
"You threatened me," she whispered, knowing her would hear. "That gives me the right to kill you. I'm sorry."
As his body slowly grew cold, Bryn felt the power of every connected wolf of his former pack mend with her and her packs minds. It was overwhelming, and so many wolves rushed to her destination at once, but they were too late. Callum was dead, and Bryn finally had the protection that her pack needed; hundreds of other wolves.
