Sakumo watched his son disappear in a beam of light and was . . . glad; not only could he move on, but it was not yet Kakashi's time to join him in the Pure Lands.

Sakumo rose to move on himself, finally free, only to be caught in an icy clasp; he opened his mouth to question, and found himself flung through dimensions to land harshly on his knees, breathless.

"Tousan?" Sakumo's head shot up at the soft voice - wavering far more than Kakashi would ever have admitted, Sakumo knew, and this was- this was his son, tiny and young and wide-eyed and- Sakumo's eyes darted down to the tanto he held, pressed to his stomach, and threw it aside as though it burned, moving instead to pull his son into his arms, tears spilling down his cheeks to land in Kakashi's hair as his son trembled against him, clinging hard enough to hurt.
