She asked him when they were at dinner if the rumours were true that his company could manipulate people's minds, since he works for the company, but he said no that was crazy.
In the last scene he was outed as a gamer who was collecting badges by going on dates and treating them as part of a game just to level-up and collect badges.
When she, his date, jumps up in disgust you see him access her account/brain and hack her brain then says "Let's try this again" ... it was true!
