The co-worker may be as big a dope as the DUmmie claims, or he may be a lot smarter than the DUmmie thinks, but either way, it was the DUmmie putting forth all the murderous and warlike ideas and the co-worker just apparently agreeing with him. Even if the guy's a complete tool, I'm pretty sure he's smart enough to tell the management that part and help the DUmmie walldude himself.
