[That line finally causes something in Aoba to break, not just because of the clear lack of trust in the words, but because of the way of phrasing that is oh so familiar - for how Noiz used to be. It's better proof than anything else that what Aoba remembers really hasn't happened for Noiz.

Finally looking up, he spits back his reply, voice raised in frustration.]

It's because I have nothing to gain from it that you know it's the truth!

[But what difference does it make? He kind of regrets the half-accusation the moment it leaves his mouth. Whatever caused this mess, it's not Noiz' fault.]

... I'm sorry. I don't understand what happened, but... I'm really not lying. I would never. Not about this.

[He didn't... make it up. He couldn't have.]
