"Says the man that responded to the only gesture I felt comfortable enough to offer, with asinine notes and doodles!"

The figures and notes he'd left every year, had taken no small amount of courage and they still gave Yamato pause, unsure if they were too much. At first, Kakashi's replies had given him hope, but now, in his anger, they felt as hollow as the comments inscribed on them and he lashed out fiercely.

He became reckless in his defence, uniform and skin splitting open as they clashed.

"I questioned everything after you left, even my captaincy! It took me years to feel like I deserved it, like I wasn't just the great 'Silver Fangs', shoddy replacement!"
It slipped out, easy and bitter as bile and Yamato struck, indiscriminately for Kakashi's throat and spat out the final barb that tore at him.

"Because no one could replace you and everyone knew it!"
The fact that he was no longer talking about ANBU, was beaten back by rage and ignored.
