The only true borders lie between day and night, between life and death, between hope and loss.

Once a friend, always a friend. Why should borders stop that?

Trees don't sneak on you."

-Brook Where Small Fish Swim

Fireheart tensed, waiting for whatever had hunted down these apprentices to emerge from the trees and attack, but nothing stirred. Feeling as if his legs hardly belonged to him, he sprang down and stumbled across to Swiftpaw.
The apprentice lay on his side, his legs splayed out. His black-and-white fur was torn, and his body was covered with dreadful wounds, ripped by teeth far bigger than any cat's. His jaws still snarled and his eyes glared. He was dead, and Fireheart could see that he had died fighting.

Fireheart dashed to the warrior's side. Cloudtail was standing stiff-legged, every hair in his pelt on end as if he were facing an enemy. His eyes were fixed on the limp heap of tabby fur huddled at his paws.
"Why, Fireheart?" Cloudtail wailed. "Why her?"
Fireheart knew, but rage and grief made it hard to speak. "Because Tigerstar wants the pack to get a taste of cat blood," he rasped.
The dead cat lying in front of them was Brindleface.

I'm going to die whatever you do, but I'm not afraid.
