As seen by the time of Tartarus' mass riot and breakout, Kai's imprisonment and the comatose status of his boss has left him as a shell of his former self, being rendered to a near-catatonic state and being unresponsive to everyone, anyone, and everything around him. This is seen where he had little to no reaction of the mass riot during the Tartarus prison break and later showed no reaction to the appearance of Tomura Shigaraki and All For One, only being able to mumble the words "Boss".
