Alex was just arriving in the town when he saw the commotion and saw the girl running away on a horse.
Alex looked a Brutus who growled almost as to confirm what Alex was thinking. 
"another angel" he said
Alex and Brutus both went to follow the girl on the horse but noticed all the other beings around her.
Alex said "too many, let's fall back and wait to see what happens."
Alex and Brutus then hung back a good distance away and watched the commotion.
