- Elias T. Walker: He's my son!
- Gabriel Rorke: [Just before he shoots Elias three times] Yeah... and he's going to get to watch you die.
- David 'Hesh' Walker: No! No! Dad!
- David 'Hesh' Walker: [When Elias is thrown to the ground next to Logan] I'll kill you, you hear me? I'll kill you, you son of a bitch! I'm gonna kill you! Mother fucker!
- Elias T. Walker: [Last words to Logan] I'm proud of you, Logan. Everything's gonna be... okay.
- Gabriel Rorke: [When Rorke puts his right foot on Elias' head, about to be killed] Oh... you are right, Elias. I'm not a Ghost. I'm the man that hunts them, and sends them back to the other side.
- Elias T. Walker: [In the introduction of "The Hunted"] There are ancient tribes, deep in the Amazon, who have perfected the art of torture over hundreds of years. The Federation embraced this heritage, enhancing it with more sophisticated methods. They kept Rorke in a hole for months... feeding him foods mixed with the poisons of exotic plants. As they broke down his body, they went to work on his mind. When his mind broke, they went to work on his soul. They rebuilt what was left, twisting him to their purposes. The process was excruciating and exacting. Rorke was their Ghost now. The perfect weapon to use against us.
- Gabriel Rorke: [Rorke somehow manages to survive being shot in the chest with a .44 Magnum and emerges from the water, then breaks Logan's arm as he tries to stab Rorke] Look at what you did.
- [kicks Hesh]
- Gabriel Rorke: You're good. You would've been a hell of a Ghost. But that's not gonna happen. There ain't gonna be any Ghosts... We're gonna destroy them together.
- Gabriel Rorke: [grabs Logan's leg and drags him away]
- Gabriel Rorke: [When looking down at Logan, about to get off the destroying plane] Hey, if you make it out of this, kid, come find me! There's always room for one more!
- David 'Hesh' Walker: [In the beginning of 'Brave New World] The Federation's rise to power had started years ago. When the great energy-producing deserts were destroyed, the world powers that depended on them collapsed. And in their wake, the Federation began to rise. The Federation united all of South America under one banner, and devoured everything in its path as it moved relentlessly to the north. After turning ODIN against us, the Federation stood on the doorstep of America, poised for the kill. They thought we were weak, crippled; prey waiting to be taken. We fought hard and we fought well. We fought them to a bloody stalemate. And here, just beyond the craters of "No Man's Land", we find ourselves in a defensive war against a more powerful enemy.
- Thomas A. Merrick: [to Hesh] You look lost.
- David 'Hesh' Walker: We're not lost. We were looking for you, Captain Merrick.
- Gabriel Rorke: [found in a Rorke file 'the Ghost Killer'] I am Gabriel Rorke. I have been trained by your Government to be a weapon. Trained to kill and destroy. All in the name of Liberty and Justice. Even surrender my very life in service to your country. But I am not one of you. The "Just" have turned their backs and become deaf to your cries. Who, then will show them justice? Who will show you the Liberty they have promised? The weapon they have created will be their undoing. But do not fear this. Do not fear me. It is only natural. Like the collapse of Rome, your cities will crumble and there will be great sorrow. But from the ashes of this diseased metropolis, a rebirth will occur. It will be paid for in blood and steel. Liberty must be restored. I am Gabriel Rorke, and I am here to show you the true meaning of justice.
- David 'Hesh' Walker: [while in a helicopter during "All or Nothing", about to land on a U.S. carrier] Merrick, we've gotta go after him! I want Rorke!
- Thomas A. Merrick: Negative, Hesh. The Federation satellites are moving into position. If they go live, the Feds can strike targets anywhere on the globe.
