[That deferral should be expected, as true to his brother as the blood that binds them to one another, yet still it scorches some part of Sasuke, a corner of his self eternally seeking approval and affection even against his will. It isn't any better to recognize its existence — that craving is as much a burden as the past. And both are woven inextricably into the same foundation. It's hardly fair, but he must remember Itachi's circumstances; blame can be set aside in light of that.]

No. [And, in light of that, he can be petty.] Not right now, it isn't important. I want to know more about this place. And you.

[The mystery of the room around them, bare and impersonal at is may be, suggests to Sasuke that his brother has been living here for some time. He's established. He has connections to others, presumably. That interests him far more than what happened before. And there is a private, irrational pleasure in denying Itachi the information he's asking for, too — however he might reason with himself it's necessary. The edo tensei is no longer relevant. That version of Itachi isn't the same as the one before him now.

Maybe his brother hadn't meant his words at all.]

I noticed Kakashi earlier. Who else is here? I can sense something, but it doesn't feel like chakra.
