Hmm Basically Ryan had a few jumping up and down moments when Reese won - he was acting very Boxing coach before they announced the winner. Massaging her shoulders then he gave her a big slap on the back/bum when she won.
The biggest thing though would be when Joaquin won and he was out of his chair again rubbing his hands together in the money sign - as in 'you owe me'. It went on for quite a bit and finally when Joaquin got up on stage he said I'll pay, I'll pay. So it seems that had a bet but there was no need for Ryan to spoil his moment by drawing all the attention to himself!
