[He's come to know that voice. Not well, but he recognizes it, and that's enough--though it sounds different, too. Too young, though the menace is all too familiar. It takes him a moment to remember the first time they met, but the memory is vivid when he does, and from that he can guess Sasuke's age; he can easily remember the sound of the Chidori, and nearly capturing Naruto, and that strange toad stomach Jiraiya had summoned. He keeps the tension out of his voice, consciously adopting a casually polite tone instead; if Sasuke is this young, then he's still with Konoha. He's no comrrade of his at this point..... but nor have they had any reason to clash by then, either.]
