I thought they mentioned that they dug it up, and they talked about Busybody in an audio meeting that wasn’t an episode of the podcast, but because it was in a similar format they forgot it wasn’t an episode of the podcast that they’d talked about it in?
edit There’s a part of me that’s wondering if Busybody is going to turn out to be the first incarnation of Dinah Dozen, and that’s why her introduction in the Guise book was partially censored, but that might be a bit of a reach.
