First off, the only reason why Ennis isn't blowing her off and kicking her on her wrinkled keester is because she is an old woman, and the wife of the D.A. And her interest in Ennis is more on the order of a bizarre little quirk of a woman who doesn't know she is being much too obvious about drooling over well built men who are out of reach. She can't really do him any harm, and she doesn't really have any power over him, nor is she attempting to exercise it. She is just being a creepy, lusty old woman.
Ah, creepy - that is the best word for Bunny. I realize that at her 'age', she probably believes what she's doing is harmless flirting and doesn't even understand that what she's doing could be construed as the female version of a lecherous, dirty old man, so to speak. She did, after all, go beyond ogling at him and got into his personal space and touched him.
Knowing how Ennis is, as we do, his reaction to her was typical and normal; he did his best to get away from and avoid the embarassing and uncomfortable situation. He was pretty 'creeped' out and I thought you did an excellent job of portraying that feeling. At least, that's what I got out of it. So real - it gave me a moment of 'heebie-jeebies, as well. Well done.
No worries!
