I know what you're saying Sharon Uri speaks all the way through like he and Michael were 'so close', but to me MJ looked a bit bored when they were together. Maybe he was bored during the vow renewal aswell and not sad after all? Shows how much he wanted to be there if he was 2 hours late!!
When Uri describes the hug that Michael gave him at his vow renewal, Uril descirbes it as being like no other hug he's ever had and said that he could feel the power (or something similar) during the hug between them both......but.....
.....to me, it looked as though Michael was just hugging Uri out of a sense of duty and not a symbol and that it didnt mean as much to Michael as it obviously had to Uri.
I did question whether MJ would let someone hypnotise him and as for asking him questions about the case against him? Well, that was very questionable too.
