FUYUTSUKI:“I have already handed the data over to Ikari.”
Dr. Nick: Fuyutsuki was about to go all whistleblower on Seele. Did Yui recruit him into her anti-Seele operation in order to save his life, as he would've surely been quickly snuffed out if he tried to go public with what he knows? Anyway, Fuyutsuki finds her plan better, so he pretends to bend the knee and returns the incriminating data to Gendo.
UrsusArctos: Given his flippant response to the incriminating material, I suspect Gendo simply used it as bait for Fuyutsuki and collected it himself afterwards, without Yui being involved.
