There is always a way

Celestia's POV:

"I am ready to do anything if it means that I can stop the trickster. So just tell me, what is it?" I asked Darius.

Darius hesitated to say it out loud. I know that it is not going to be an easy task. The way Darius hesitated made me feel even more anxious. 

"Saber of Venom is the only weapon which is strong enough to eliminate the Silver Shadow," Darius answered. "The Venom of a serpent has the power to destroy anything or anyone. I suggest you stab the Silver Shadow with the Serpent's saber right at his heart."

My heart almost stopped after hearing that. Should I have to stab him with the saber? But I can't do that! When I thought of stopping Theo, I meant it as subduing him and throwing him in the dungeon. But I should have to eliminate him?!!!
