Peter frowned. He mourned the loss of life, the death of someone who must have been vibrant and amazing, to have made such an impression. It was as though she'd given one last hardship to her killer, something to haunt him for the brutality of her death.
He reached into his coat for his backup plan, and withdrew a bag of blood. Peter hadn't expected nor been willing to offer Aidan his own vein - not for his sake, but for his friend's. Giving his blood hot from the vein might have awoken those predator instincts again, the ones this was meant to help quell. So Peter had thought ahead, and gotten a couple of bags ready.
"Aidan... I want you to try this instead," he said, offering the bag of his own blood. "It might help, or it might not... but the option needs to be considered."
They were both nurses - they knew what five or six bags of blood a day could mean to a hospital. At least this supply could keep up with Aidan's need, and hopefully help to pacify it.
