If so, aside from the obvious expansion reasons, why use the perfume?
I'm guessing it
is a perfume container but it doesn't actually look like the others. On the other hand, neither did the one Miriam used on Jacqui, which this also doesn't resemble. (Was it clearly established that Miriam discovered that the perfume was responsible for what was happening at the SJI? There was no mention of the samples when she was in the kitchen with Mallory, yet she knew to take them with her when she left. Unless she already had more in her bag...) I did wonder if this might be a container she was going to exhale Réka's spirit into. But I suppose the perfume is more likely.
The pop-up text is from Queen Mab by Percy Bysshe Shelley. That character though was apparently first described in Romeo And Juliet - a fairy who essentially puts dreams into the heads of sleeping people. A key part of the Wikipedia synopsis of the Shelley poem may be: "Queen Mab detaches Ianthe's spirit or soul from her sleeping body and transports it on a celestial tour to Queen Mab's palace at the edge of the universe [or Jacqui's place, whichever is nearer]."
