Sad to see IS go Hope this will cheer you guys up a bit
[Rooftop] Eto attacked Sasaki; Sasaki's life in danger and turns into Kaneki (?!) A three-way battle between Eto vs Tsukiyama vs Saski and Kanae (I am confused because logically Tsukiyama should pair with Kanae?) Kanae's clothes were ripped off, revealing her gender
[noro side] Three side character investigators (does not include Ito if that's what you are wondering) are dead; Q squad and Kuroiwa vs Noro (implying they aren't dead at least); Noro's mask broke and face revealed; Someone took a picture of Shirazu using a smartphone (Hori Chie??) As Noro and Urie were facing off, Shirazu calmly took some photo evidence (of Noro's face) using his smartphone; Saiko still could not move; Noro's alarm went off, Noro retreated but Urie wouldn't let Noro escape
[furuta side] Matsumae has fallen; Furuta is an one-eyed (?!); To keep his identity secret he killed off the remaining investigators with Kijima's chainsaw quinque
[Ui side] Ui at the staircase (lol) communicating with Washuu about status quo, saying that the ghouls actions are suspicious and CCG's operations details might have been leaked
[Back to rooftop] Aogiri ghouls were scouting nearby. They spotted Washuu's helicopter and reported the location to Eto. Eto makes her move. It seemed Tsukiyama had known Kanae was a she all along, but never laid eyes on her (naked) body to respect her privacy; Tsukiyama stared at Kanae's (now revealed) body and commented on how "bony" she was (ゴツゴツ - rugged, angular - the same phrase Kanae used to describe herself in a dress Ch 52 so I used IS translation "bony")
