Itachi hears. He hears everything. He hears his leader's confident voice give out instructions (orders) as to what to do next.
He hears his partner's mumble about how he can't wait to chop off some limbs. Itachi hears this clearly but does not say anything. Not a word.
Itachi hears his brother's yell (mixed with agony and hatred) as he comes dashing towards Itachi; chidori fully charged and crackling with power as it is directed at him; leaving a trail of gravel behind it. He easily evades the chidori while at the same time, grabs his brother in a choke hold.
"You're weak. You lack hatred." He coarsely whispers. His brother only replies in a fierce glare. The Tsukuyomi appears in Itachi's eyes and Sasuke screams as his world is filled with pain.
Itachi does not hear these screams.
Itachi does not hear the screams (of fear) in his dreams, either. He only sees the images; the images of betrayal in their coal eyes as he slays them with no regret what-so-ever. He sees the reflection of the Sharigan in their eyes, too. But they are too trustworthy to think that he'd even harm them. But they were wrong.
But their blood is as real as it was when it first spilled onto the ground.
"Please! Please! Don't kill me! Plea-" the man's cries went abruptly silent. Itachi stood over him, observing the leaf nins mangled body. Itachi didn't hear his cries, either.
But Itachi hears everything.
Author's Note: I'm sorry if you're confused. It's just a random one-shot about how Itachi seems to hear everything but hove no outward reaction to it. It's just a drabble really, I hope you enjoyed reading this! Don't forget to review!
