Redtail Rise standing on the edge, face up

His response, physically, is immediate. His hackles rise, his nose wrinkles but he does not show teeth - not yet. The change in mood is sudden and it takes him a second to understand the challenge within the threat. This is not a fight for injury or death. She strikes just as he understands her intentions and her teeth grip his shoulder, quick as a snake.

Ratio has the weight and size advantage, he does not pull away from her, nor attempt to throw her off. For better or worse, his strategy has always been to endure and keep his enemies in close combat. To give her space would be a detriment to him and so he swings his head toward her and shoves forward and down onto her. His jaws part, aiming to grab her neck, shoulder, back - whatever part he can use to grab her and pin her underneath him. 

He will not injure her - he is in control of himself.
