Aziraphale saw it coming and gracefully arched his head back, the ball flying overhead, albeit not by much.

Oh bugger. He was going to have to land soon. Well, if Barnaby could be on the roof...

Flying while facing the direction that Loki had shot at him from, Aziraphale sailed through the air and landed on top of the manor's roof, folding in his wings and ignoring the burning sensation in his back. He really needed to do that more often.

He took a deep breath, readied himself, and ran to the the edge of the roof that Barnaby had just gone off.
