Morrison will be on the side of 'all succubi and incubi are evil', but he doesn't mind angels as they are believed to be allies in the fight against evil. So he's okay with Carl, but not with Steph. And he cares about Ethan, he sees a lot of himself in the boy, so anyone touching Ethan will have to deal with Morrison. He sees value in Mike, is indifferent towards Benjamin, doesn't trust Gaia, and is inclined to see Harriet as an ally.
I'm looking forward to learning what Jase really is ^_^
