The regular agents all ordered whatever they wanted (minus a drink) but each and every one of the Numbers ordered a Big Mac combo meal. They didn't know how to disobey orders so Cobra was baffled by this choice.
"Why did you get drinks when I specifically told you not to?" he demanded.
"We don't intend to drink them," Eight replied in his usual monotone. "We ordered the first thing on the menu because it was most efficient."
All five of them had done it without even consulting each other. They really were programmed robots without an individual thought among them. Six going rogue had become even more of a mystery after watching these guys the past few days.
If this group of Numbers all automatically made the same choice in the name of efficiency, how on earth had one of them randomly decided not only to ignore a kill order but to protect his target?! It didn't make sense at all given what these people (if you could even call them that) were like.
