During the third round of testing, Cia realized Roman must have what?

Cia then begins to flip through Roman’s practice examples and notices that he did not attempt to answer any of the questions except for the first one. Cia realizes that Roman has manipulated his team, and he has actually answered all five questions, which is why it took him so long to complete "one" room. This way, when his teammates go into their agreed-upon question room, they will be punished for re-trying a question he already solved. Cia tells Brick her suspicions, and he casts her opinion aside. Cia is adamant, though, and does not go through the door to answer her question.
