He knew everything that happened here. That Evil God knew.
It means that he knew already of our strength. And how Veronica is here as well. As for Celestine, I did say that I didn't know her other than what Veronica told me. But the Archbishop must have told the Evil God that I probably knew Celestine and she's with us as well.
Then there's the werewolves and the serpents. And Cooldra as well. The Archbishop must have telling the Evil God about my strength and my familiars as well. Though I don't know if the Evil God knew about what happened in the other battlefield.
Let's see, he saw us jumping down the cliff. He might not be able to tell what monsters I have with me that got transported with portal to where his familiars were. But his familiars could tell him about my familiars they were facing. So the Evil God must have known about my familiars by know.
Except for Victoria.
