Stranger Things Season 4: Where is Kali?

One of the bigger supposed “plot holes” inStranger ThingsSeason 4 has to deal with a character that hasn’t appeared in the show since Season 2. As some may recall,Stranger ThingsSeason 2 sees Eleven run away from Hawkins to meet with a girl named Kali, aka Eight. Both Eleven and Kali were raised in the Hawkins Lab and experimented on by Dr. Brenner, and they even used to play together as toddlers. However,Stranger ThingsSeason 4 sees One,aka Vecna, kill all the kids at Hawkins Lab, an event that takes place years before El and Kali are reunited in Season 2.

This “plot hole” can be explained away by simply saying that Kali escaped prior to the Hawkins Lab massacre. And in fact, she must have escaped well before any of the time the Season 4 flashbacks take place, as she’s nowhere to be seen during any of the experiments. After all, Kali has unique powers that allow her to manipulate people with illusions. It stands to reason that powers like that could be very helpful when it comes to escaping from somewhere. Not only that, but Eightismentioned in Season 4, though briefly, when Vecna (when he’s known as orderly Peter Ballard) talks toElevenabout the time her mother tried to take her from the lab, more or less confirming the theory that she simply escaped or left before the massacre occurred. Despite this, it seems someStranger Thingsfans online aren’t satisfied with this explanation.

Stranger Things Season 4: How Can Eleven Speak So Well in the Flashbacks?

Another issueStranger Thingsfanshave had with Season 4 is how well Eleven speaks English in the flashbacks. As some may recall, the Eleven fromStranger ThingsSeason 1 had great difficulty talking and could barely speak much at all. The residents of Hawkins that El interacts with in Season 1 basically have to teach her how to talk, and so manyStranger Thingsfans were confused when the Season 4 flashbacks showed Eleven speaking much more fluent English than she should be able to given the series' timeline.

However, there is an explanation for this, and an official reason at that. In an interview with TV Line,Stranger Thingscreators the Duffer Brothersexplained that the trauma from the Hawkins Lab massacre caused so much distress that it caused her to regress. The official timeline for Eleven, according to the Duffer brothers, is that she goes into a coma after the massacre, and upon reawakening, is isolated in the lab. She represses the memories of the massacre and regresses developmentally.

So just like the Kali situation, this supposedStranger Thingsplot hole actually has an explanation.

Stranger Things Season 4: Will’s Birthday

Will Byersis becoming one of the most-talked about characters afterStranger ThingsSeason 4, for a variety of reasons. One of these, unfortunately, is due to a plot hole, and it’s one that doesn’t have a real explanation. It’s been known for some time that Will’s birthday is March 22, and that just so happens to be the day that Mike, Will, and Eleven go to the rollerskating rink in Season 4, Episode 2.

Despite the fact that it’s supposed to be Will’s birthday during the scene, none of the other characters mention it. Will is acting moody throughout the episode, which one could think would be due to the fact that all his family and friends forgot it’s his birthday, but he later explains that he was feeling down about being a “third wheel” when hanging out withMike and Eleven, and that he was annoyed about El lying to Mike about how life was going for her in California.

This is a genuine plot hole that’s been acknowledged by the Duffer Brothers, and so fans shouldn’t expect to see it resolved inStranger ThingsSeason 4 Volume 2. It’s possible that theinevitableStranger ThingsSeason 5will make some effort to correct this oversight, but that remains to be seen. It’s most likely a plot hole that was only mentioned by the franchise’s most diehard fans anyway, but still, it’s understandable that fans would like to see it acknowledged in some capacity.
