"Umino Iruka... I see you've been caught into this city's web as well.."
If Iruka stiffens slightly in surprise, he doesn’t really think he can be faulted. He hasn’t heard that voice in years, and even though it’s deepened with age, he can still pinpoint exactly who it belongs to.
He looks over his shoulder, then turns fully to look at him. “Uchiha Itachi,” he acknowledges with a level of dispassionate calm that would surprise most of the other citizens of Hive City who have had the misfortune to deal with him late. He doesn’t know Itachi, not really; Iruka’s years older than him, ran in different circles than the youngest ANBU, but they’d both spent years in the same crowded mission room before the massacre.
“Yes. Quite the setup they have here, isn’t it?” He isn’t sure what Itachi wants — hell, Itachi could simply want a familiar face after years as a missing-nin —but he doesn’t feel obligated to ask.
At least if he’s everything his gruesome reputation led people to believe back home (although Iruka has always personally struggled to connect the Itachi he knew with the infamous missing-nin), he can’t permanently kill Iruka here.
