Kevin is a high level technician working for the Department of Defense.
Reese and Mark Snow, under duress from Kara Stanton break into a secure DOD cyber-warfare development lab and use Kevin to upload a virus into the DOD servers. When Stanton locks them inside the electronics lab and escapes, Kevin overloads the room's power supply, causing an emergency shutdown. The emergency battery activates and Reese and Snow destroy it to open the doors of the lab. Reese thanks Kevin and tells him to stay put to keep him out of harm's way.
