Here's a thought, which I formed after I'd watched this episode at last saturday, and it's about Manny's revelation. First of all, he is not the only angel that we have seen in this series, but in the same time he isn't the Fallen One, because God cast Morning star from the heaven, and we believe his wings were stripped at same time. But Manny still has wings and his wings are still white-ish, while the other angel had black ones, and she couldn't stand sight of our beloved Manny.
And he said, "I will cancel Constantine's contract," and the reason for that is, "because Bruharia works for me."
In theory we have seen Manny working for the Lord and being highly against the Enemy. But in hypothesis, he is claiming to be in a pact with the Devil. Here's a thing, can God cancel Constantine's contract, or does Morning Star have power of the Lord with his "business" bollocks?
