The Godzilla Show's Confusing Timeline Explained
The next point we see on the timeline in the first five episodes of "Monarch: Legacy of Monsters" is just a couple of years before the main events of the story. Episode 4, "Parallels and Interiors," explores Kentaro's backstory and shows how he met May. While stewing in anxiety over his first proper art show, he randomly bumps into her on the street in Tokyo. The two have an immediate chemistry and end up spending the evening together, drinking, talking, and eventually going back to Kentaro's apartment.
These scenes take place a year before the main story, as the captions tell us. That would put it sometime in 2013 or early 2014. It also means that May and Kentaro saw each other for a substantial amount of time before taking a break. The art show takes place well before G-Day, as Hiroshi is still around (though not in the ways Kentaro would like).
This isn't the only 2013 scene we get in the show, though. In Episode 1, right after the flashback of Bill Randa on Skull Island, we jump forward to 2013 and see his discarded pack of Monarch records get recovered by a Japanese fishing boat. It's unclear how exactly the pack got from the deck of a fishing trawler to Hiroshi in less than a year, but it's the same pack found by Kentaro and Cate when they search their father's Tokyo office. Clearly, Bill only bought the best gear for it to have survived at sea for so long.
