Sasaki lets out a huge kagune and it pierces Tsukiyama.
Sasaki: Special Class Ui.
Sasaki: I will annihilate him right now.
Ui: …Alright. I’ll handle the one on the other side.
(referring to Kanae)
Tsukiyama: (So this is… the path… you’ve chosen…)
While Tsukiyama is still pierced using Sasaki’s kagune, he hurls him out of the building.
Sasaki glances at Kanae’s direction.
Kanae: Hah… Shu–
Ui: (He’s going to help him…!?)
Kanae chases after the falling Tsukiyama.
>Sasaki arrives at the Qs’ location.
>Urie: Shirazu is…
>Urie: He wanted to see you.
>Urie: If you just…got here back faster, he’d…!!
>Sasaki: …Is it ‘my fault’?
>Sasaki: Who was the one fighting along side him, Urie-kun?
>Urie: (Me.) …
>Sasaki walks past Urie and says something into his ear which startles Urie.
>Sasaki: All the drawbacks in this world is due to the insufficiency of the person’s capabilities.
>Sasaki: …If you wish to curse someone, then curse your own weakness.
Note that Sasaki is actually Kaneki, but he's pretending. Also, I'm a bit dissapointed if this is his true reaction to Shirazus death. I didn't expect a break down from him, but even more emotion than something this cold would have been nice.

From the scans, hes shown hugging Shirazus dead body. He still cares, but him giving that line to Urie is a bit unexpected. Probably going to see some sort of use out of him eventually. He knows he has capability.
