"Right," Octavius says, albeit a touch uncertainly. Privately, he's not sure how larger groups will protect against a demon (or an abomination) who is that committed to subterfuge. But Barrow seems like he's got control over the situation, and if there is one thing that has not changed about Octavius in the intervening seven years, it's that he will always be lulled into a false sense of security by an authority figure taking charge during a crisis. And so he follows along without objection.
