21 lasts for 1 minute and 50 seconds. For the first 1 minute and 35 seconds, The Announcer makes the following speech (a.k.a. the 21 speech) after which there are 15 seconds of silence until the end:
"Glyph was sedated. He was trying to tell me about a book he'd found years prior in a library at his family estate. He asked for some water. I gave him one glass of water and he began.
The patriarch of his fathers bloodline was a lord in 18th century London; an early investor in a time when investment was novel. With a handful of well-timed trades, the patriarch accumulated a fortune that still exists today. He earned enough to re-write his personal history; editing himself into the nobility and erasing his common past. The only record of this deleted data was a diary the patriarch kept as a young man.
It was filled mostly with recipes - he had worked as a pastry chef - but one page described an unusual meeting in 1720 that was not pastry-related. The future patriarch witnessed a fire in a small shop. The building bore no insurance mark so no one rushed to save it. He and a handful of bystanders watched the blaze. In that moment, he wrote, he understood himself to be outside of chance. The bystanders - now friends - had glimpsed a forceful motion; relentless and perfectly concealed, that could create and destroy and lift entire societies into the sky.
Glyph asked for an additional glass of water. This time I brought him two.
Something is going to happen ... in 21 days."
The glasses of water mentioned here seem to be a callback to the quote from How to Pronounce 65, "turn off the lights & drink a cold glass of water". Perhaps that was said to Glyph? Maybe he suffers from headaches, or something similar, and/or more sinister?
