Scipio’s style of interrogation has always been to motivate people to talk and get out of the way of those already motivated. He needs to direct this discussion a little, but only with a few words here and there. (This is a lot more specific than the monologue Astoria Troy interrupted, which wasn’t really revealing any more information than “Yep, we’re all Cultists, all right.”)

Byronvision!

These berserker spirits seem to enter through wounds, fatal or otherwise, as they did with Byron this time… but what happened to Brother Tom’s body demonstrates that they can also enter by other means. I’m not sure every instance of spreading the Madness has involved these otherworldly demons hiding in the black-magic FX, but if not, the way they enter and bond with their hosts creates a purer strain.
