With Stranger Things season 4 in the pipeline, audiences can’t keep themselves from speculating what is in store. With the bread crumbs that the Duffer Brothers have left, fans all over the globe are trying hard to connect the dots. But there are some things we can be sure of. One of those stranger things is Eleven’s “siblings” or Hawkins Labs’ test subjects.

We are not in Hawkins anymore
Stranger Things season 4 is highly speculated to bring forward other test subjects from Hawkins lab. Recently, a piece of news is making rounds on the internet. It quotes Millie Booby (Eleven) saying that she was not a big of Stranger Things season 3’s ending. Well, we believe Millie Booby would have loved it if she knew what was in store for season 4.

We all bore witness to the final battle at the Starcourt Mall. And we all saw Eleven lose her powers. Additionally, it has been established that the Russians have a Demogorgon.
Since a Demogorgon cannot survive if the door to the Upside Down is closed, the season 4 world is pretty much doomed.
So, who will fight the underworld evil? Unless the Duffer Brothers rush to a half-cooked explanation of how Eleven gets her powers back in Stranger Things season 4, there is only one answer.
Meet the Stranger Things’ Test Subjects
Just like Eleven (aka Jane Hopper), we saw another child who escaped Hawkins Lab. With this came the revelation that there are others like her with diverse mind-powers. Kali showcased her ability to web illusions and distort reality.

Their names imply that there are at least 11 such kids (test subjects) in the Stranger Things world. While two have already made their way into the series,
Stranger Things season 4 might be in preparation for bringing the Hawkins Lab’s kids’ fates together.
We have discovered five of Stranger Things Test Subjects (apart from Eleven and Eight). Scroll down to meet them!
#1 The girl in the Rainbow Room is not Eleven!
Apart from all unknown Stranger Things test subjects, one has made it to the screen. Remember when Eleven’s mother shows her a flashback of her memories? In an effort to find her daughter, Terry Ives (Eleven’s mother) breaks into Hawkins lab. And in the process, she finds ‘the Rainbow Room’ in which two girls are playing.

One of them is Kali and that was established without doubts after Eleven’s aunt shows her an article titled ‘Vanished! Indian Girl missing in London’.

But against popular theory, the other girl in the rainbow room is NOT JANE HOPPER. Why? Because Jane Hopper is a brunette! Got you thinking? We went further down the road and reached a seemingly possible conclusion:
Sara Hopper is alive
Hopper is alive and kicking in Season 4 of Stranger Things
And she could be the girl in the Rainbow Room. A popular fan theory has established many-a-times that she never died. Even if Sarah Hopper is not the girl in the rainbow room, it is highly likely that she is one of the Test Subjects of Hawkins Lab.
Apart from this, we zoomed in the news clippings in Amy Seimetz’s hand when she showed them to the most popular Stranger Things Test Subject, Eleven. DKODING them, we have found four out of the remaining (unknown) eight kids at Hawkings Lab.
#2 Cleveland teen girl missing in Indiana
The surest test subject in the Stranger Things world is a girls-basketball team captain who went missing when she was 16. She mysteriously disappeared after leading her team to victory “somewhere between the Indiana junior-high gymnasium and the bus waiting”.
What must have grabbed Terry Ives’ attention (and ours) was this line. “’The girl’s widower father describes her as a genius,’ and unusually strong for her age. Neither he, nor the police, consider the girl a runaway.” More interestingly, the report further suggested that she was spotted in Indiana.
Everything comes back to Hawkins, doesn’t it?

(By the way, did you notice that her mother is not alive? She surely could have been a part of the same experiment that Terry was involved in.)
#3 Another Girl Lost
We know the least about this Stranger Things test subject since her news clipping is hidden completely behind ‘the Cleveland girl’.

#4 Baby Boy abducted from County Hospital
This Stranger Things Test Subject is proof that the test experiments were not specific to girls. The news clipping narrates the story of a baby boy’s abduction reporting that a nurse was found dead at her home.

What raises the suspicion alarm is that the nurse “had called in sick for the last week before arriving unexpectedly to work yesterday. The newborn baby was last seen in this nurse’s care.” Stranger Things indeed!
#5 Someone from California
Stranger Things season 2 introduced two characters from California: Billy and his sister Max. While we have met Max’s mother and seen enough of Max to know that she cannot be a Stranger Things test subject, Billy is unknown territory.

His mother is missing and not much is discussed about her. Moreover, Billy is seen as a troubled (and handsome) kid. Since one of the (partially hidden) reports in Terry Ives’ file points to someone missing from “San Diego”, California; we suspect it might be Billy.
A wild guess can put his powers inclusive of creating doppelgangers (which we also see in Stranger Things season 3).
So, it is likely that Billy is alive in Stranger Things season 4 and he has powers just like Eleven
Forget Hopper, these three are the strongest contenders to ‘The American’
With Will Byers back and audiences still in awe of a classic yet mind-blowing concept; no one could have imagined another season based on Upside Down. With season 2, when Eleven closed the gates, the possibilities of another season surrounding the underworld seemed saturated. But with season three, it was established that the makers have a pretty creative mind.
What do you think? Could Billy and Sara Hopper come back to life? Share your views in the comments.
