Sizemore
In one universe where Jenny Everywhere was a fictional character, a man called Michael, also known by the name of Sizemore, was a writer. By his own admission, his output consisted of “a lot of dull political tracts, some book reviews, short stories” and “a terrible novel.”
He was a heavyset man with a beard, making him resemble a Viking. Spurred on by his Scottish friend Boag, Sizemore discovered that he could write himself into Jenny's narrative and, thereby, functionally interact with her, since by definition the version he wrote about would exist somewhere in the Multiverse. He abducted an incarnation of Jenny who was currently in bed with Ringo Starr and took her back to his home despite her attempts to shake him off by shifting rapidly through eight different universes. There, he revealed to her that she was fictional, and rewrote bits of her life before her eyes to prove it. Ultimately, he wrote this version of Jenny out of existence altogether.
The next day, Sizemore woke up with his girlfriend Jess and looked over the prose draft he'd written, bitterly reflecting that his friend Boag had gotten him to write something extremely strange. (PROSE: Paperback Writer)
