Naturally, don't expect it to be easy. It would really be more of a case of convincing him that the angels make a better meal, because as far as he is concerned, everyone's a meal.
And well, the Angels are a harder target, as they are pretty powerful, and there is a few of them. Where as the others are less in number and power. And probably tastier.
Angels are actually like the main course taste wise I would think, considering their raw power alone would make the levvie feel accomplished for ten minutes, but yes, others are more... accessible. That's the barrior that would need to be passed for anyone attempting to recruit him; why spend the effort of taking out an elusive angel when demons grow off trees crossroads, and humans one fatal lure away?
Pretty much. If he was at the rank of say, Dick Roman or Edgar, his logic would be more easily appealed to and he would be considerably more dangerous in that respect. Alas, Redmond isn't quite that high on the scale.
My logic is, why try to take on powerful archangel like Atlas when there's easier targets. Meat is meat, I don't think they have taste preference. I mean, unless they like accomplished kills, sure. If you persuade him enough to want to try to eat an Archangel? I'll be impressed.
I suppose it's up to the folks at the diner, as the levvie is at the door :)
Honestly, I would be surprised if they convinced him to do anything... provided they figure out his true nature, as that isn't the easiest thing to spot unless they want to follow in what will probably be his plan to eat the waitress.
Well now I have some things to think about. Plans to make, meals to prepare. I mean its not the first time Micheal has had to cook for someone else. /wink
