So there was a spy . . . for some unknown party that doesn't have any existence in this world, and nobody else from their faction would have reincarnated here, so whoever they are they have no allies and no cause now. And which furthermore, whatever else they might have been, certainly weren't the outfit pushing the whole "Treacherously kill everyone with the forbidden spell" schtick. Hmmm . . . good enough reason not to just wax Lucas? Not so sure about that.
