Episode Twelve: "The Choice"
"Hitman with a heart of gold" is a tiresome cliche, but it's all in the execution. (No pun intended.) Sure, it's a bit much to suggest that someone who makes a living killing people even the CIA is uncomfortable killing would suddenly get cold feet about an assignment because Brody and Carrie are good people. But the way Peter makes this announcement to the odious David Estes – sitting calmly, immobile and gravelly-voiced and wielding a silencer-equipped pistol while wearing gloves, in the armchair in the guy's bedroom – is menacing to the max. After all, a hitman with a heart of gold is still a hitman.
