Greggory spins the sword in front of him as a defensive measure, only to begin coughing as the smoke bomb fills the room.  He makes his way up the stairs to discover the dead victim and his unconscious Knight Captain, still holding the dagger.

He picks up the fallen captain, shaking his head, and once again carries her back in the direction of the castle.
