Stranger Things Season 5 has got dedicated fans dissecting the episodes, and now they have found continuity errors. A chorus of viewers is calling out what they believe are significant narrative inconsistencies, particularly surrounding the history of Will Byers.

Fans discuss alleged continuity errors in Stranger Things Season 5

The criticism intensified following Episode 4, titled “Sorcerer.” This one features Will recalling key memories, including a flashback of a young Will and his brother, Jonathan, happily building the iconic Castle Byers on a sunny day. This cheerful scene received immediate backlash, as it directly contradicts Jonathan’s emotional description of the event from Season 2.

In the episode, “The Mind Flayer,” Jonathan tells a possessed Will a very different story. He recounts that they built the castle on the night their father, Lonnie, left for good, working through pouring rain and subsequently falling ill. Fans were quick to juxtapose these two versions.

Jonathan once said that when he and Will built Castle Byers, it was pouring rain and they both got so soaked they ended up sick for a whole week. And it also makes no sense for them to act so normal when it’s literally the day their father left the house ?‍♀️ ? https://t.co/fnQc7l8of5

“Jonathan once said that when he and Will built Castle Byers, it was pouring rain and they both got so soaked they ended up sick for a whole week,” one fan noted on X (formerly Twitter), adding, “And it also makes no sense for them to act so normal when it’s literally the day their father left the house.”

This isn’t the only continuity error in Stranger Things Season 5 that viewers are talking about. In another Season 5 episode, Joyce mentions Will was 11 when he was taken to the Upside Down. However, eagle-eyed fans point to a canonical missing persons poster from the show’s first season that lists his age as 12.

This has reignited discussion around “Birthdaygate.” It was a prior continuity issue from Season 4 where the show seemingly forgot Will’s birthday was March 22. The Duffer brothers previously acknowledged that mistake.

Some fans have tried to rationalize the Castle Byers flashback as a possible happier memory before the rain started. But the consensus online is that this is a clear production error. After five seasons filmed across nearly a decade, such continuity snags are perhaps inevitable, but the show’s intensely devoted fanbase remains its most meticulous critic.

With Volume 2 releasing on December 25, viewers will be watching every frame for further clues.
