When Swift announced on Thursday morning that she would be dropping her surprise eighth album at midnight, she thanked songwriters Aaron Dessner, Jack Antonoff, Bon Iver, and someone named William Bowery.
Fans were quick to notice that Bowery was the only one whom Swift didn't tag, and some dedicated detectives discovered that there are no registered songwriters or producers named William Bowery.
So, going off the theory that William Bowery was a pseudonym for someone else, fans began to investigate deeper.
As it turns out -- according to fans and some paparazzi photos -- Swift and Alwyn were spotted outside the Bowery Hotel in New York City back in 2016, toward the start of their romance.
Fans searched Alwyn's Wikipedia page, which reveals that he is the great-grandson of English composer and musician William Alwyn. Hence, according to their theories, William Bowery is actually Joe Alwyn.
