Ares let the pout melt away, a self-satisfied smirk came in it's place. He openly checked her out, he liked her attitude as long as she did not direct it at him. Mortals really should learn to recognize gods and goddesses, they also should show gods, especially him, some respect.
"You should be more careful all alone in a place like this." Ares was not going to apologize for startling her, he never apologized. Why would he? The God of War does not apologize! "Someone very dangerous could just walk up to you and hurt you." As he spoke Ares let his true power flash in his eyes long enough to show that nobody was as dangerous as him.
