The brief chat between Ikari and SEELE that follows simply establishes that Cirus won't be leaving the story any time soon. Fuyutsuki and Ikari's banter is simply a logical interaction for the pair to have until Ikari reveals a new stage of his plan. Using Rei (he does that a lot, doesn't he?)
Now we get to one of the more interesting scenes in Kenosis. No one knows exactly what Ikari's agenda is, and Rei is in no mood to play his games. Unit 14 gets her attention, and more of what happened to Cirus is hinted when the black Eva goes berserk just to get close to Rei. The cute/disturbing sequence where the Eva holds it hand to Rei's through the glass is one of my favorite moments in Kenosis. I also get a certain catharsis from Unit 14 slamming its fist into the wall to make Gendo go away. Ikari isn't stupid enough to test whether or not the thing would actually kill him (would do so in a heart-beat, just to confirm for you), and so he plays his card carefully, getting Rei to come with him. Ayanami-sama is intuitive, strong, and I love her, but I thought it realistic for her character that in such a crazy situation, she would be unsure how to help Cirus or what to do. She knows part of Cirus is in there, so she tries to protect him. There's not telling what Ikari will order for a rogue Eva that obviously wants to kill him, so she gets Unit 14 to shut off for the time being, as only she could. Like with Cirus, she can control the behemoth with the gentlest gesture. This is something Ikari could never understand, and why Rei is so much stronger than he will ever be. The scene wraps up with another brief show of Ritsuko's warming character, happy to keep Unit 14 off the junk pile.
Always happy to write a scene focusing on Ayanami-sama, it was the most desirable starting point for the next Angel battle. I think it's quite touching and cute when she squeezes his hand softly, and her inner pain just tugs at my heart-strings even so long after writing the story. The scene is simple, but touching, continuing to show Rei's affection for Cirus. The one line about her uncertainty of 'how much of' Cirus is there with her shows her intuition about the Unit 14 situation. As is revealed later, there's enough of him there to hear her. This small scene ends with Hyuga's notice about the next Angel's arrival ('unidentified object' is synonamous with Angel in Evangelion).
The battle with the Angel is quite simple. I wanted to give Shinji some quality page-time, showing I'm not blowing him off as a character, show off Unit 01's rage powers, and also demonstrate that I can be as odd as the creator of Evangelion in my designs for Angels. Rei and Asuka hold their own, but still get injured quite a bit. I do feel bad about injuring Rei in battles, but that's exactly the sympathy I want the reader to feel. The "how could you hurt her!?" notion, which will hopefully home in on the Angel rather than me... Rest assured, I would never permanently harm Ayanami-sama in my stories.
The chapter does end rather abruptly. After all, these chapters were cut-up after the story was written, so in some cases they're not as smooth as they should be. Shinji is back to himself, helps the others back to their launch pads, and the battle is done. In case it's not obvious, the chapter title comes from Shinji's use of Unit 01's berserk power. The paragraph explaining his break-down into fury is supposed to help that be more clear, but it hardly matters.
