The seventh floor was his last step before going up to the dormitory to catch some sleep. He was tired from climbing up the stairs and sneaking around and using the charm in various places at Hogwarts.

He entered the hallway where the entrance of the common room was and pointed his wand at the wall on the right. "Caelum Saepio!" he said as he drew an infinity shape with his phoenix feather core wand. Then he walked to the next wall and performed the same shape and incantation again. The boy yawned loudly as he walked to another area and did the same "Caelum Saepio!" spell there. Then he put his wand back in his wrist holster and walked towards the portrait of the Fat Lady, said the password and entered.
