Jimmys brother is actually doing everybody a favor keeping Jimmy out of the firm. Business is business no matter if you're family or not. That's the tough part. Just cuz someone's feelings might get hurt you can't do something completely irrational. That's just plain stupid.
It's like when Michael Corleone says to Tom, you're OUT!

Now Jimmy just has to UP the amount of cash to a nice number and go with it.

Mike is great. You know what they say about a man of few words or the "quiet ones". Those are the most dangerous or the ppl with the most skeletons in their closets. They are always one step ahead of everyone and you never see them coming.
