"Pietrson, you've established the connection?" the first man to enter auxiliary control demanded.
"No, sir, we seem to be blocked from an outside source," reported the first guard.
The first man turned to Shelton. "Where's the block coming from? How do we get around it?"
"Beats me. Your buddy Pete's the one at the controls."
The first man made a hand gesture. Pietrson stepped back, and two other men pushed Shelton forward.
Shelton grudgingly took the center seat. "You're experiencing feedback from the primary control room. The system is giving it precedence."
"Can you fix it?"
"There's nothing to fix, the program's working correctly. What you're asking me to do is exactly what the program was designed to prevent, there's no way around it."
The first man looked at the fifth man. "Sean?"
"He's lying," Sean said.
Pietrson slapped Shelton across the face. "You're a pretty bad liar, science-boy!" he hissed.
Shelton glared. "All right, because the people in the control room are logged in under my account, all I have to do is convince the computer that I'm actually down here via a security question, and it'll lock them out."
"How long will it take?"
"Five to ten minutes."
"Lying," interrupted Sean.
Pietrson raised his hand to slap him again. Shelton started typing. "Okay, one minute! Done."

"Not me," Montgomery said, brow furrowed. "It's what someone else did..."
