Wait, what connection do touka and shinohara have for her to take flowers to him im confused..?

They’re actually quite well connected- not personally but technically, they go way back. 

Touka served Shinohara before the 20th Ward raid when he visited Anteiku to ask about Kaneki

Well, kind of. There’s a reason he recognised her

Shinohara, along with Mado, were in charge of the Corpse Collector Investigation. They were directly responsible for hunting down Arata and sending the CCG against Touka and Ayato as children. And of course, Shinohara was also a wearer of the Arata armour.

Ghoul Investigators snooping around Anteiku right before the raid would have been something that stuck out for Touka. He pretty much lost his life in that battle, where he fought Yoshimura (Touka’s father figure) wearing Arata (Touka’s actual father)… so even if Touka doesn’t know just how far their history together goes, there’s a lot of connection within the story.

As for why Touka took him flowers, we can’t be 100% sure.

But ever since murdering Mado, and certainly after the Anteiku Raid too, Touka has made a huge effort to let go of any feelings of vengeance. To let go of the anger she held in the past which had always weighed her down. 

It was something she tried to teach Akira too, because she had already been through this. 

So I’d like to think her leaving flowers for Shinohara was her own way of letting go of leftover hurt from the Anteiku Raid. A gesture of peace, maybe forgiveness, to someone who had also lost something on that day. But we’ll see! I’m curious to know if we’ll find out more.
