Touka and Hide meet again, of course because they have the same goal. Consider the manga discussion Tokyo Ghoul: Re chapter 149 follows.
In chapter earlier in Tokyo Ghoul: Re the point of view of the story shows how the confused and continuing CCG troops racked their brains to find ways to defeat the Kaneki monster.
In chapter this, the viewpoint turns to a member of Goat led by Kaneki. If the CCG thinks of a way to kill Kaneki's monster so as not to increase the casualties, it is different from Goat's members who are thinking of ways to save Kaneki alive.
Starts with Tsukiyama who is very depressed with this incident, considering this purple-haired man is very fond of Kaneki. According to him, Kaneki is a good person, he also still has a human heart even though he is Ghoul and has killed many Investigators.
Tsukiyama deeply feels sorry for Kaneki. In his current state, he can not read his favorite book, drink his favorite coffee, or hold his son later.
Before digressing further, Nishiki stops Tsukiyama's words, and says that he also feels the same. Finally one by one Goat members began to express the greatness and goodness of Kaneki.
Until finally to Touka. Touka desperately wanted to save Kaneki, because he wanted to inquire about their son's name to King of Goat, arguing that Touka was not very good in Japanese. All of them just smiled and understood.
Moving to another location, Akihiro Kanou, a genius scientist who had mengopers Kaneki into Ghoul was visiting his mother's funeral, according to Hide's account chapter earlier.
Based on the theory, Kanou should have the key to this problem, and can find a way to defeat the Kaneki monster, therefore he is sought after by CCG members, but Kurona first finds him (for always following Kanou).
Kanou hopes to visit her mother's funeral calmly, and Kurona immediately takes out her Kagune. Kanou also explains all the findings of Furuta about the previously ignored Ghoul, now beginning to unfold.
Furuta also comes from the Washuu clan, and Washuu is one of the cannibal clans in the eastern country (if following its original mythology, the land is Arab). Washuu clan is a Ghoul clan that always practiced cannibalism, so Kakuja had risen first even when they were born.
Due to this, Kanou uses Rize as a research material that happens to belong to the Washuu clan, and Kaneki is a prototype of the Kanou experiment. Kurona is also angry that he and his brother are also part of Kanou's experiment, and he plans to kill Kanou directly in this place.
Unfortunately, Kanou himself is not concerned with all that stuff. He prefers to kill himself using a shotgun. Kanou apologizes to Kurona before he fires his shotgun, he dies.
The CCG party found Kanou's lifeless body, and indicated that he had committed suicide. But this is not an end, because the assistant of Kanou came and brought all the important things related to this experiment.
Return to Goat organization. They are still thinking of ways to save Kaneki. Since the Merpati of CCG are busy evacuating residents, this is an advantage for Goat. They plan to approach the Kaneki monster and look for a gap, then dig into Kaneki's body, looking for his real body to be.
Ayato hears a noise, and Touka takes the initiative to approach him. It was Hide, along with Amon and Akira. Hide asks if he wants to dig up the body of Kaneki's monster, Touka is shocked.
Approximately, what is the reason Hide came to see Goat? Does this mean Goat is in the strategy Hide has in mind. If so, then the cooperation between Ghoul and man really can happen, what do you think?
