In breaking dawn if a fight did break out. which side do you think woul have won the fight and which side would have lost ? 

The Gaurd rearranged themselves in a arrow-shaped formation Demetri leading at spear point. Their actions were measured, deliberate. Our  reaction  was more disorganized. Snarls and hisses ripped through the air as we took off straight to our deaths.
