I'm gonna wait until Drake gets a chance to start his stuff before introduce the antagonist. In fact, his character would probably be the best to introduce the antagonist to. Alex and Maeve are doing their own thing and Felix seems to be more the type to involve himself in others' business.<br/><br/>In fact, Drake, would this idea work: Felix doing a summoning after finding out about the antagonist or... maybe not the antagonist specifically but in response to becoming aware of other summons? Perhaps he is learning about exorcisms when they suddenly come across a flesh and blood supernatural creature instead of your typical, everyday possession.
