In "The Once and Future Flash," Barry raced eight years into the future to try and find a way to stop Iris from being murdered by Savitar. When he got there, he discovered that his pals went through a lot of changes, and most of them pretty awful. One person who did well for himself was H.R. Wells, who we saw owned his own coffee establishment, became a successful author on Earth-1, and earned a legion of amorous fans. The twist comes with the fact that the books and signs advertising Wells all have his face printed on them.
