I do like the actor who is fast making Chad his own. (just as was done to Brady, Will, etc.)
Oh, I think Chad wants Abby to eventually find out that her reinstatement at the hospital was because of him. Thus he stays in the background, not blowing his own horn, but Abby learns what a nice guy he is.
And then Ben? Oh, Chad purposed wanted to push his buttons, get Ben to show his temper, not fight back, etc. Again, Abby sees that Ben has a tendency to get violent. That was Chad's objective. Sonny has now warned Ben, who has told Sonny that Chad likes to push his buttons.
And Ben has a point....he apologizes to Chad for the punch, is sorry, etc. And what does Chad do? Tells Ben how he is the one who took Abby's virginity. That was a low blow, and something guys just should not ever discuss or mention to anyone.
Ah, Chad is "appearing" Mr. Nice Guy" but really is rather sneaky and underhanded. well done, though.
