Dialog taken from the Official X-Files web site from the episode Existence. (lost scene)...

Mulder: You say these human replicants are unstoppable. How do you know? Skinner and Mulder stand above Krycek, who's on Skinner's sofa. Lifting a can of Coke to his lips with his prosthetic arm. Krycek: You saw me run over Billy Miles, man was dead meat and got up and walked away. What do you need? Mulder: I need to stop them. And I'm curious how it is you seem to know so much about them. Krycek: Hey, I keep my ear to the ground. Skinner: Good. You'll be spending a lot of time on your hands and knees where you going, Krycek. Krycek smiles, taunting Skinner back, as he finishes his Coke. Mulder: Don't get too comfortable. As Mulder turns to leave. Krycek: You get me a cold one Mulder? Mulder doesn't even turn around. Exiting Skinner's office. Skinner looks at Krycek holding up the can, ignoring him, too. Cut to: Int. FBI Hallway - Night - Continuous. Mulder moves down the hall to the elevator. He pushes the button and waits, but the elevator seems stuck or something. He changes his mind, decides to use the stairs, exiting into the stairwell. Camera drifts up back to the elevator when we hear a ding, the doors opening now...revealing Billy Miles (NOT in scrubs)
