I agree in that I wouldn't like to see Clemenza betray mike, since he was loyal in part one. On the other hand, wouldn't that preface make a "clemenza betrayal" more effective in part 2? I think it would have delivered a harder punch knowing that clemenza stayed loyal to the end by killing himself in prison and keeping his mouth shut. But then again, we wouldn't get the chance to see Pentangeli drink out of a garden hose and call champagne "champagne cocktails..." haha
