Dun keeps his sole eye on Ryusei's back, but lets the kid go. For all of Dun's concerns, Ryusei actually hasn't done anything else suspicious. It wouldn't be fair for him to douse him in a bucket of paranoiac warnings and rage when Kengo had done the exact same thing as Ryusei did in trying to determine the exact nature of the place. His cousin had accused him once of holding grudges against people, even to those who don't deserve it. Ryusei is no Guan Yu and is yet to be a threat to Dun. There's probably no reason for him to be overly concerned about the teen.

Once the door's shut, Dun brings Kengo to a separate room. There are some completed dummies, but there are others that still need stuffing. Dun picks up one and tosses it at Kengo.

"It's not difficult, but it's tedious. Between the two of us, we should be done by two hours."
