What an awesome review, my dear! *gives two thumbs up* And I have to say I agree with it!

I don't believe Zachariah speaks for Michael

You know what, I'm starting to believe that, too. In fact perhaps it's Castiel who speaks for Michael. Michael is not supposed to be a dick. He is merciful and graceful though he is very, very harsh for all the demons. And perhaps as an Archangel it's not his job to 'persuade' his vessel.
