He makes it our business. [Slightly irritated, but only because this is another problem to pile onto the mess of problems he has already.]
I can look past a sabotage; that's not important, but a murder not so much. If Acumen's anything like Sentience was he can scan inmates' thoughts--preconceived plans, motives, you name it. [And this wasn't picked up on?]
