'Don't freak?' That didn't bode well. Part of the young exorcist wanted to argue, but Rin's stance and expression stopped him for once. He could handle anger or panic, but that kind of strain on his brother's face...

He stood slowly and moved for the door, fixing Rin with a short, searching look before stepping into the front room.

The new boy entering the room looked far too young to be a doctor of any sort, and his cracked spectacles and shaggy hair (abnormally shaggy for him, anyway) did little to age him, nor did his wide-eyed look of shock when he realized just who it was that Rin had brought with him. The recognition was nearly instant, the missing years on Shiro's face unimportant.

A quiet little noise forced its way out of Yukio's throat before he could clamp down on his vocal cords, but after that holding his tongue was a fairly simply task.

After all, what can you possibly say ten seconds after setting eyes on the man that would become your father?
