He went a bit ham trying to satisfy people I think, like, combining the 'Recollection Room'/Gallery with the actual plot to make it part of the story itself probably wasn't something he originally was gonna do, and the fact we had 0 warning or preview of Administrator/Quinella unlike every other character also makes me think he added her last minute to justify the Recollection Room being something 'more' (As her role there is a bit reminiscent of Dark Sakura in the OG version of the Nero game I believe). Administrator's words getting blurred in that one scene was probably meant to not 'Spoil' something she will do that will actually affect Kirito for real and wouldn't be revealed until later, it's just that people went and read it from the game's files anyway XP
