[ Initially, confusing her was not his intention but when he gets that kind of reaction, it confirms what's been on his mind and Kaneki hesitates visibly. Had something in her code been tampered with when CERES 'brought' her here before him? The thought isn't a nice one by any means so he attempts to push it aside to focus on the damage he's already done.

Once they're out, Kaneki turns to face her with a bit of sadness in his eyes that he's unable to hide from showing as he regards her. ]

I'm... not sure why it is that you don't remember, but... all of that happened after Banjou came to Anteiku that day. There's more to it but... I can try and explain it all when we're not in this park if you'd like.

[ Part of him half expects her to get mad at him or something, his mind piecing together from what she said into what she must remember last. Mainly that since she mentioned Banjou or didn't even remotely remember anything he said, it must have been around the time the man came to the shop looking for Rize, but before Ayato and Yamori came and everything changed for him.

He still remembers that day, too. Making quite an impression in managing to knock out Banjou with such little, unintentional effort which had really made him surprised back then. Now, the man and him had become acquaintances since then and a world of events had occurred inbetween then and now that seemed so long ago. ]
