Sam knows exactly what he's doing. After he kissed Angie....and I do believe he made the move on her ...he mentioned something about her morals...as Ang had referred to kissing George as morally wrong because he had a thing going on with one of her friends. He must have given her the hickey....clever...very clever
Yeah the Hickey thing is kind of odd... I mean what happened there? More must have gone on than what we saw.
