The lifeguard spaceship escaped into space, heading to the separated escort fleet. A few of the Abandon mothership crew members knew the demon emperor had abandoned them. He was on the run.
Yet they could not make a noise. The lives of their generations were at stake here. Announcing the escape of the demon emperor from the battlefield will lower the morale of the alien alliance fleets.
The war will fall apart.
When questions are asked, the one who exposed the information will be found. He or she is automatically the scapegoat for the loss of the war, and all their bloodlines will be cleansed to wash off the stain on the demon race's historical streak of victories.
They have to keep their mouths shut. They can't expose the escape of their emperor; they can't escape the sinking mothership; they just have to do what they need to do and await their deaths.
