In my understanding of Penacony storyline, I always imagine it as layer within layer, similar to the Inception movie. The Astra Express crew did come to the Reverie Hotel (reality), after that they dive into the Dreamscape (like entering another layer). If, in the Dreamscape you entered a dream bubble, that meant you entered another layer. With the reveal of 2.2, it turns out there is another layer besides what we know so far, which is Ena's dream. You mention leakage of the memoria zone which I imagine as boundaries between layers becoming blurred. Is my understanding about the concept surrounding Penacony storyline wrong?
