Recap of and thoughts on Infinity Train Book 4 and the series as a whole · 7:27am Apr 18th, 2021
As many fans speculated, Book 4 - Duet takes place in the past, specifically in the mid to late 1980s. While I'm excited when HBO Max announced a new season, I lowered my expectations since it focuses on a new set of characters. Usually, there's a guest character in the 7th episode of a season and the next will focus on that certain character. For Book 4, it's a totally different story and timeline.
