Artemis- Loop in the Feed

The mere thought of Root gave Artemis the shivers. He decided to
check in again. He inspected the monitors. Juliet was still in the kitchen,
scrubbing at the sink. Washing the vegetables.
Captain Short was on her bunk. Quiet as the grave. No more bed
banging. Perhaps he had been wrong about her. Perhaps there was no plan.
Butler stood at his post outside Holly’s cell. Odd. He should have
been on his rounds by now. Artemis grabbed a walkie-talkie.
“Butler?”
“Roger, base. Receiving.”
“Shouldn’t you be on your rounds?”
There was a pause. “I am, Artemis. Patrolling the main landing.
Coming up on the safe room. I’m waving at you right now.”
Artemis glanced at the landing cameras. Deserted. From every angle.
Definitely no waving manservant. He studied the monitors, counting under
his breath . . . There! Every ten seconds, a slight jump. On every screen.
“A loop!” he cried, jumping from his chair. “They’re feeding us a
loop!”
Over the speaker, he could hear Butler’s pace quickening to a run.
“The safe room!”
