This movement is quite excellent.To avoid simply me-tooing, I'll bring up something that nags at me every time Zach Stephens makes an appearance since S3M4: Gudrun Truemace's recognition of him as "Zachiel Firewheel". Are we ever going to find out what Mr. Stephens is, Celestially speaking? My best guess is an In Nomine-style Ofanite. Not sure how an Ofanite came to exist in a setting that seems to be bereft of the other Choirs (and indeed, other Ofanim), but I'm sure Gryphon can make perfect sense out of it.
