Haise keeps the mask. Despite wanting to return it, Uta manages to persuade him into keeping it. This makes it the third time that Uta has gifted Kaneki with a mask (this last mask twice).
We are also made aware of, as many of us have surely suspected, that Uta's eyes are like that because of a tattoo and not because his kaguan is activated 24/7.
Haise also asks Uta if he makes custom made masks. Though short it was imo the most interesting part of their conversation, because Uta hesitated before answering, it was just a second but still. It might be that he thinks there's more to that question than meets the eye, to me there are several explanations:
-Haise came to the conclusion that uta might've crafted masks for ghouls, and would be able to pair customer/mask together.
-Haise was talking about using the Q's special abilities to their advantage. He might want to try and infiltrate the ghoul world, and
for that, they'd need masks,
S1 Squad part: Ihei is scaryyyy~~! Such a beast. Her abilities are definitely up there with the cream of the crop, easily dodging and launching counterattacks without breaking so much as a sweat. And there's also Fura's comment on her being scary, probably both strength-wise and fear-wise.
Kijima... Well what can I say, I never liked the guy and I like him even less now. He's totally going to go all russian mob on Yuuma (the captured ghoul).
Take & Arima in the same squad again.. I don't think that's a very good move on the bureau's part. Take seems like he's really tired of Arima's attitude and leadership, there's probably going to be some sort of confrontation but I doubt Take's going to stray from his calm and collected demeanor.
Takeomi knows Yoriko, maybe they dated? Doubtful though since he called her by her surname.. Maybe they went to school together before Takeomi entered the CCG Academy? Very plausible
