Well for any Roya lewd events, there are no differences that I can think of, because the look stays essentially the same (so far) the entire game.He's talking about the gallery room, which I'm assuming when you replay events in the gallery, he wants Aura's appearance to match what she actually supposed to look like in those scenes.
And as for real world events, I'm less sure, but I don't think the events keep updating to Aura's current looks?
So I'm not sure what the issue is...
