At first I knew because we all found out in the program. Enoshima's AI was what was brought into the program and hijacked it; she orchestrated everything that happened and later left clues for us so we could figure it out. She wanted to lure in Naegi and his friends, but...

[The way they found out... well, it was a good way of building despair, wasn't it? As they discovered more and more, they realised more and more. Hinata did, at least, can recall well the weight that'd sunk into his stomach, how much he didn't want for it to be true.]

But I've remembered, too. Some things when she was talking to us. And then more since then, after we got out. [He looks down at his palm, flexing his fingers.] All of the terrible things that I did...

[He drops his hand, frowning, looking up to her again.]

Please, believe me. It's...important. I didn't want to believe it, but I had to. I had to accept all of the things I was responsible for.
