It took five minutes after he was told that the AI of Unit 01 was, in fact, the other universe's version of Yui Ikari for Gendo to order everyone else out of the lab. They stare at each other; the Supreme Commander of NERV and the soul in an avatar body, as Gendo pulls over a chair and sits in it.
"It's been a while," Yui says.
"It has," he responds, "For you. You did it. You went and you did it."
The avatar nods, studying the needle like fingers.
"I had to," she says, "There was no other way."
He nods, silently, as she walks, tethered by the power cable and landline, walking over to another chair and sitting in it herself. She folds bladed hands in her lap, the body, based on Rei's appearance, almost a match for her own. She could be no older than her 30's in that Core, having gone through with the initial contact experiment years ago.
"It has been some time," she says, "Some time since I could speak, even if it isn't my mouth. I could tell some things are different on this world. How is our son?"
He is silent, staring at her. She stares back, tilting her head, waiting as he taps his fingers on the armrest and finally finds the appropriate words.
"You sickĀ bitch."
