Hmm. Did I ever mention my Nicodemus gets a redeemed and has a 2nd chance at life (reincarnation, soul put in another body) and takes the form of Malcolm Dresden.
So first, we have bad Nicodemus who respected Maggie Sr. taking aggressive steps to do what she thought was needed, etc.
Then we get Nic in the end gaining "sainthood".
Archangel balances out a "cheat" and is allowed to send his soul back in time, into a new body.
Malcolm Dresden meets Maggie Sr.
I know it doesn't answer your question but it touches upon my theory. So, there...
Oh, and I'm going blind seeing all these topics.
