10 years

Roman Atwood's age is displayed as 35 years, with his birthday listed as May 28, 1983, while Brittney Smith's age is shown as 27 years old, with her birthday listed as February 16, 1991, and a calculator displays the calculation 27 - 10. The video then cuts to a man at a podium with two other men, one in a suit and one in a military uniform, and then to a man walking down a hallway with a gun.
