[At that killing comment, Guren puts one arm in front of Dextera in a guarding motion, the other gripping at his sword. Embarrassing. He knows it's like a neon sign here, and especially useless when he's feeling weaker than usual from blood loss, but if it's going to be a fight, he'd rather be in a ready stance. He has no idea what to expect from Crowley at any given time. It's all guesses. And that angry voice is frightening, he won't lie.]

He didn't. I had a feeling. Take it as a lesson and move on. You can get your blood fix from me. That should be enough.
