You're really going to do it, aren't you? You're really going to go back to war? Gregor said. He could feel something boiling up inside of him. So, we'll just forget about what happened. The jungle, the Firelands, the Bane. His voice was rising and he could feel the rager side of him taking over. Forget about everybody who's dead! Tick and Twitchtip and Hamnet and Thalia and Ares! And your parents, Luxa! And your pups, Ripred! Let's just forget about everybody who gave their lives so that you could have this moment where you could — could make things right again! So you could stop the killing! We were fighting for the same thing, remember? You two owe each other your lives! You owe me your lives! And now you stand there and ask me to choose between you? To help you kill each other? Gregor yanked Sandwich's sword from his belt and swung it so violently that even Luxa and Ripred stepped back. Well, guess what? The warrior's not fighting for either of you!
