William looked down at the kit still clutched in his hand. He could always trust Byron to jest about his fastidiousness.

There was a knock at the door and William wearily shook his head. He walked over to the door and threw it open.

"All right, you win. I concede..."

But his visitor was not Byron. Out in the corridor Tamara cocked her head and lifted an eyebrow in amusement.

"Well, if you insist."

With an almost musical sound, Byron shimmered into ghostly being just behind her and stuck out his tongue. "Ghosts do not knock, my handsome young man. That's for the corporeal set." He wiggled his eyebrows at the siblings then evaporated into nothingness once again.

"I hate it when he does that," William groaned.
