Goodman Grey Transformation ...

Definitely one of my new favorite characters. But in my head canon when he jumps Blood on His Soul/Ursiel did he transform into a flippin Loup Garou?

Bob did say Loup Garou a aren't limited to wolves but based on the description Harry gives it seems exactly like a Loup Garou type of beast. It would also make sense how he was able to hang with such a powerhouse.
