I've seen a few people theorizing that Entry Number Seventeen was Gaster creating a Dark Fountain, and they usually point to the lines DARK DARKER YET DARKER THE DARKNESS KEEPS GROWING and THE SHADOWS CUTTING DEEPER. These make sense, but there's another line that supports this theory I haven't…

Wing made the design for the DT extractor, but Alyphs was the one who actually physically built it. "Using the blueprints, I've done it..." or some variation thereof. Wing's work seems to have been in timelines, as Sans frequently references these in situations such as his fight.
