I have always been intrigued by the Tom Hagen character and I have questions for anyone who care to elaborate.......,

1. Why was Tom really out when Mike took over? Was it really a Scilian Thing and the fact he was Irish?

2. In GF2, during Michael's meeting with the Senator, The Senator told Michael that he knew of his plans to take over a Casino. Then the camara's flash to Mike and Tom with unpleasant looks on their faces. What was this all about? Was this something that Tom was not supposed to know?

3. When Mike told Tom right now he is the only one he can trust, was this another reason why Tom was out of the Family and apart of Mike's legitimate business, so he could have someone he could trust?

4. Finally, toward the end of GF2, why does Tom stare at Fredo, Is it because he knows that Michael is getting ready to kill him?
