I'm going to go more feral and articulate about it later but
Not with a bang but a whisper, Dot got their italicized oh (Realization) here and it's devastating, and 2) their exchange with the Foldlight was a consumption/transmutation of their metaphysical "humanity"; not that the Foldlight ate it but that the instruction & manipulation of reality requires a person to BE like a Foldlight with the fold and light within themselves. It's possible that now only the Fold remains within Dot and that is synonymous with the detached serenity of Motherhood, like a chemical reaction that has equalized into its new state. Perhaps Artifice discorporated because he was already a Mother and "empty", or else the internal light-fold composition of a Mother cannot survive the command/exchange, or he just didn't have a crowd of his friends adding their input to the Foldlight which was in this case almost certainly "I hope we get home but I also hope Dot survives".
"The Granddaughter lies beside the Foldlight, dead. They open their eyes" signifies pretty clearly to me that they are a Mother now. The death is a spiritual one of identity. They are not the Granddaughter anymore. I wonder what their Mother name will be, and also, I am SO hyped that the narrative followed through on their journey to Motherhood. It was a sacrifice but also in a very Mother-approved way not a sacrifice but instead a Transformation (and Dot's original goal). To me this is phenomenally more interesting and rewarding than either avoiding Motherhood (a bit too have your cake and eat it too) or dying outright (the full sacrifice theme Rawfield rightfully decries, renders Dot simply a martyr and cuts off further exploration). The Mothers are SO interesting and a S3 where we get to see a "before and after" character's journey and more insight into Motherliness because they are a protagonist is very exciting. Also, what will happen with Cleo - I don't think it will be possible for them to have a relationship like they once might have, and navigating this new space will be characterful and fascinating.
Also. DOORS!!!!
