The doors of the control room swooshed open, and through them stepped a bleary-eyed Stormtrooper, carrying his helmet under his arm. Yawning, he looked up, and was startled to see the others before him. 

"Hm? Oh! Right then, one sec." He shot forward into line, placed his helmet on, and snapped to attention with a salute. "Private Davvik reporting in, sah! Forgive my lateness, sah!"

If anyone could see under his helmet, they would've seen a very worried face.
