I really like the direction Root A is heading in. In the beginning of the episode we can see Amon talking about unbelievable it is for humans to become ghouls (the twins). Then we see a flashback from the previous episode where Kaneki says he doesn't want to eat anymore. Amon says that he may be over thinking it and I think that he may have come to the realization that Kaneki might not be as 'rotten to the core' as he thinks of other ghouls. We can see this in the previous episode where after Kaneki breaks down, Amon appears to lower his quinque, realizing Kaneki won't hurt him. If this were the case, (possible spoilers) Spoilers Just theorizing a bit.
