[He wish he could be more surprised by that admission, but he's not. He's not shocked, but he is sad, sad for Kaneki, and all that he's gone through. He should have had a happy, ordinary life. In another world, he and Ken could have been friends without all of this other stuff muddying the waters.

Ken's - Sasaki's - life is complicated, and he only knows the tip of the iceberg.]

I'm sorry. That you -- [No. No, that's not right, is it? Sasaki doesn't want to be known as Ken, and he has to respect that.] That you have to remember that. If they're trying to kill you, you have to do what you have to do. I understand that. But I hope that there are some of them out there, people who were only just changed, maybe, that you can save.

For both you and them.
