A flutter of wings; an empty, distant sound that followed Obito wherever he travelled. Or, more specifically, when he was hunting someone down. Echoed screams that died off as fast as they came to be when he flew past something--or perhaps it was all just in his own mind. The sound of fury. He was going to keep his promise to Obi, Itachi wasn't going to be killed. But he was going to break.
Obito halted on the other side of the training ground. Itachi was in his sight, and he could smell and hear the filth emanating off of him. It made Obito eerily calm, content even. At least by appearances. A blink of an eye and he stood a few feet behind his other nephew. "Itachi," he hummed, with the familiarity he spoke with when in the company of a relative.
"I haven't seen you in a while." His eyes flicked to the targets that Itachi had been attacking. "Under some stress, I take it?" It wasn't uncommon for him to, in a sense, psychoanalyse people he was close to.
And he was good at pretending that he was close to his prey.
