This page exists for exactly two reasons. 1. To let the reader know that Buscemi really is English and has now been fully taken over. 2. Give readers one last chance to clearly see the barcode, for those who got into this story late. After this page it only appears once by mistake. It’s in the article image of the page where the last SBaHJ is shown. I forgot to remove it from that particular image.
Given the second reason is just an ARG hint and ARG doesn’t really have much story significance, I have no real explanation for why English gave it to us. Maybe it was the same kind of a glitch that happened with Vriska, although that is unlikely. I think it could just be Lord Buscemi wanting to give us a way to find his temper tantrum. Oh yeah, one of the ARG puzzles was finding stray numbers and letters from about otherwise identical bazillion lines of ”WHY DONT I HAVE AN OSCAR”.
Also one of the barcodes is different, letting the ARG players know what set of alphabets/numbers to use in a deciphering process.
