The Emily audio was uploaded to Soundcloud at roughly the same time as the Architect sent us the glitched image. So the audio (even if only as a backup) was part of the operation package from the start.
Kind of daring to post it to a public Soundcloud that had been used to contact an Operator though if it was meant to be used as a backup.
That is interesting, due to the fact that it is a poisoning of a "hired academic", which it may be possible that our employee,Emely, which may be the poisoned individual in said book, but possibly in a more metaphorical sense, which Idk how much makes sense that makes but it's a theory. another is that the quote refers to a favorite ale inside a pub the detective enjoys, so it possibly has to do with the restaurant in the clear image in London and the possible ties to it's more Italian winery and fancier look to it.
