Well, this is a little less... scenic than outside a ramen shop, but Minato almost wants to laugh at the question. Word for word, this sure is Shinjiro. Instead, he settles for smiling a bit, though there's something sad about the smile, for this question really highlights for Minato how similar things must have gone for both him and his sister. Including Shinjiro's fate.

He manages to keep himself from looking at where the bullet wounds had been, instead forcing his thoughts on the present - this meeting, the new start they all get here. The question Shinjiro just asked him.

Scuffing his foot on the ground absently, Minato replies, "A future."
