The final season of Stranger Things could have a surprise.

There may be an important connection between the latest series of Stranger Things episodes and season two, by far the most poorly crafted to date. One episode in particular received the most critical acclaim of the entire series.
However, Stranger Things writers took to Twitter to urge fans to reconsider their opinion on season 2, calling it “constantly underestimated”. Information about the second season has led fans to hypothesize that an underrated character from the second season, considered by many to be the least successful of the series, is returning to the show.
this is aboutenigmatic and ambiguous character of Kali (Linne Bertelsen) pseudonym Otto. So far, she has only appeared in episode 7 of the second season, but due to various unresolved issues regarding the second season, she can be included again in the plot of the final act of Stranger Things. In addition, Season 4 revealed additional details about the experiments done on children in Hawkins Lab, and who knows the plot surrounding the character of Kali couldn’t be explored better.
Young Stranger Things stars Millie Bobby Brown, Finn Wolfhard, Noah Schnapp, Gaten Matarazzo, Caleb McLaughlin and Sadie Sink will return to the cast of the fifth season.
