Kdot, I have a potential plothole I'm wondering about. When Connor is trying to drive out the demons, he says "God the Father commands you! God the Son commands you! God the Holy Spirit commands you!" That doesn't work. He eventually realizes that the right thing to say is "I command you!"
If Connor is Christ, which is what I'm hinting at, then the first three commands should have worked. It's one thing for those to fail to work when a priest says them, since some demons are too powerful, especially Legion, but when Christ issues those commands, they should have worked. In the New Testament, Jesus barely broke a sweat casting them out.
Thoughts?
