I disagree somewhat. In Mrs. Choc's case she will have to come to grips with the shame of her actions herself. It's not Choc's job to ease her guilt. If anything is going to have a chance to be rebuilt she'll have to come to grips with her wrong, and then prove to Choc that she's trustworthy.
That doesn't mean he shouldn't show compassion and love or hold it over her head. HE doesn't have anything to prove, she does. If she never recognises how wrong she is in giving something she was witholding from her mate then he's probably better off without her anyway.
