He offered to model for Frank and challenged him to take better photos than the ones he took. If Frank failed to photograph Kent as he requested, he will fail this scoop and Kent will not be encountered again. If you please, you can kill Kent in this mission. If you attack him, he will say "H-hey! Cut that out! I'm a pacifist!" But if you kill him, you can take his handgun, and it will say 'KENT SWANSON IS DEAD" across the screen. This prevents him from ever showing up again, and you get a handgun.
