The 'Mastermind' states he is an accountant. Elliott says he's NOT the accountant, as Elliot worked with the Accountant taking down Hector Madera. Possible reference to the movie The Accountant (2016).
It was 22 years between jobs with Noah Wyle and Joey Slotnick working together in Pirates of Silicon Valley (1999).
