I found going to the church in Badon REAL interesting, and loved that the more things happens, the more the MC is thinking "am I in WAAAAAAAAY over my head?" The whole meeting with Philip was great too. He treats the whole thing as serious and if he is unaware of who Metatron really is (doubtful, given that MC's parents know of her) he hides his surprise very well.
I do have a minor complain, but it's just because of the way I did things. I delivered Ina to the Knight Commandant (looking forwards to her artwork) then did the Badon stuff. The narration about it says he's not sure if the Knight Commandant is there - but he would know where she is because he met with her, in delivering Ina. I'm not sure how difficult it would be to change the wording slightly if you deal with Ina then deal with the Badon piece, Might be more trouble than it's worth *shrug*
Given how Maya acts, I'm thinking she's the relative age of MC, Sam, and Celica. Also thinking you should have Sam and Maya team up for the lolz over who's better at "say something then 5 seconds later brain catches up". Maya would PROBABLY do better, but not sure...
Jealous angel is cute...but still think I'd be wary of ticking off someone who can slaughter a (whatever the heck that creature was in the temple). Still waiting for Ashley to come to the MC saying that one of her pranks on Metatron went wrong or (even better) Metatron started pranking her back!
