Fox Gabriel was introduced to us by Ximon. He can be seen chatting with Eli, at the beginning of the final ritual, and he steals the knife away from Jonathan, towards the end. He also stood in for Cary Gladstone, as Policeman #1, during the final ritual scene, when Cary had to get back to another production he was in. If you look closely, you can see that it's Cary who helps Stephen Doyle grab Jonathan, but by the time they get to the altar and start tying Jonathan down, it's actually Fox.
