In that scene from GF2 when Michael confronts Tom about another job offer in Vegas, Tom said that he turned them down......but he did look a little nervous.....I mean, who wouldn't, Michael was a monster.....but that answer was not good enough for Michael, then he got personal. Do you think that Tom was really considering that offer, and he just told Mike he said no......and Mike new better.....or was Mike just showing Tom how it can be with him, if he were to dessert the family?
My opinion is that he wanted to let Tom know how mad he would be if Tom did decide to leave the family.
