Did Allie and Michael dislike one another, or just indifferent?
I think it was more of a case of mob royalty and Sonny bared the grunt of it when Mike was coming up .
Lil Allie got to enjoy all the money and power, but we know who is sleeping in there own bed at night.
Also I thing there was a lot of jealousy going on Mike hit it good with the gas racket and Allie got the power...
