One Way Out

You watched Ethan hoping he was okay. Deklan rushed towards him, ready to help. As he got close, Ethan stopped shaking. You prepared to let out the breath you were holding when you saw Ethan pull out something. Deklan couldn't see what it was from his angle but you could clearly. You open your mouth to warn Deklan but you couldn't.
Ethan turned around and you caught a glimpse of his yellow eyes. He rammed Deklan onto the ground and stabbed Deklan with his giant steak knife. He jerked it out and pushed it into Deklan's chest again. You heard someone scream.
