"Is it done Sergeant?"

"Yes sir. I just finished the adapting signals to the past. Now we just need to test it."

"And what are the precautions?"

"Nothing really that dangerous. Just a few electric shocks or more. Or maybe a few other harmless things."

"Good. I want it starting at 2:30 this afternoon sharp."

"Yessir. I'll call in the test subjects."
