When they first found out Ichika-chan could eat human food, Kaneki and Touka were feeding her and tried baby food which went surprisingly well. Once it did and she wanted more, he burst into the cafe (where there was Yomo, Uta, Hide, and Nishiki) and yelled “SHE CAN EAT HUMAN FOOD!!!” and Hide’s first thought was to ask if they could feed her a lemon and film it

I like the way you think. 

The door nearly flies off its hinges. Kaneki stands in the frame, panting, double-over, shaking.

“What’s wrong?!” Nishiki yelps.

“SHE CAN EAT HUMAN FOOD!” He shrieks. Behind him, Touka appears with Ichika in her arms and a dry look on her face.

“That’s what you were freaking out over?” Nishiki snickers.

“That’s wonderful.” Yomo looks like he’s about to die of joy.

“I’m happy for all of you,” Uta says calmly.

“Can we feed her a lemon and film it?” 

Everyone turns, slowly, to Hide, who sips his coffee. “It’d be so funny.”

“Holy shit! Why are there are nine kakugans staring at me!” he shrieks.

“Good!” Yomo bellows.

Touka shakes her fist. 

“I’ll eat more than your face this time,” Kaneki growls.

“Get in line.” Nishiki seethes.

“Uh, I’m her father. I’m first,” Kaneki protests.

But behind all of them, Uta catches Hide’s gaze. He winks, with a slow nod.
