Quentin asked scornfully, "Who are you?"
He couldn't possibly be Big Brother, right?
He could understand why the Big Sister shown to the public was a fake—No. 028, aka Big Sister, wanted to keep her identity a secret. Judging from her personality, she seemed like a relatively low-key person.
But surely the Big Brother in the lounge couldn't possibly be fake as well, right?
… even if the man in front of him did look a bit like Big Brother!
While Quentin was thinking about it, Justin withdrew his gaze. Instead, he smiled and said, "I'm Big Brother."
Quentin: "!!"
He suddenly sneered, "Can you make up a more reliable identity for yourself if you really have to make one up? What a braggart! That's so unrealistic!"
