Well, dt, he sounded convincing. But then Fredo said that Johnny Ola said, "there'd be something in it for me..." Then he launced into that rage-filled diatribe against Michael--"want respect," "passed over," "send Fredo to do this," "smaht, not dumb..."
What could that "something in it for me" have been, given all the insults, slights and bad stuff Fredo attributed to Michael? Would he-- could he--have gotten anything if Michael had survived whatever Roth and Ola planned in the Tahoe attack? I don't think so. I think all the things that Fredo wanted could only have been gotten if his brother were dead.
