Macaque blinks a few times, going still for a second when Epsilon is mentioned. Sometimes it bothers him a little, sometimes not, but it's a minor detour. He has bigger things to focus on.

He blinks again, though for a different reason, when the trinity is mentioned. It's sure a comparison.

"We've done some explorations that went reasonably well, and Lucifer is nothing if not careful." It'll be fine.

Of course Macaque is going to be a little nervous at subjecting his precious daughter to anything that might hurt, but it's necessary.
