Kakashi smiled, his mask and sloped hitai-ate doing an excellent job of disguising the almost pained expression on his face. The Uchiha were a.. difficult clan, to put it lightly, and though Kakashi's experience with them started and ended with Obito and his connections, Kakashi understood enough about them to understand exactly what Sasuke meant.

Kakashi didn't have a clan to disappoint, he had no family to depend on him - all he had were these bonds he'd forged for himself, and Sasuke was one of them however pseudo-professional their relationship seemed on the exterior.

"I understand," he nodded, not patronising or pitying in the slightest. "Then should you need me, find me, and I assure you not a word will make it back to them."
