The reappearance of Vecna in Stranger Things Season 5 is not all about big, scary and cool effects, but it is a deeply psychological trick. He was not bragging when he took Nancy Wheeler and showed her a vision of the future in the previous season. He was attempting to manipulate the characters by frightening them into making specific decisions.In this vision, Vecna revealed that Holly Wheeler and her parents would be his new targets, besides the destruction of Hawkins. This served two crucial purposes, firstly, it moved the plot, and, secondly, it struck Nancy on an emotional level. She was suddenly made to realize that she wasn't just a normal girl and a reporter anymore, she was now up against a supernatural foe who is always one step ahead. It destroyed her faith and made her doubt her ability to defend the people she loves and cares about.To the other members in the group this warning increased the pressure. It compelled the characters to move quickly and determine how far they would go to rescue Hawkins. Vecna was not only attacking them physically but using fear as a weapon, and that makes the fight even more dangerous.Why did Vecna reveal the future to Nancy in Stranger Things Season 4 View this post on Instagram Instagram PostVecna's visions are always personal; he reveals to people what will hurt or shake them the most. Nancy wasn’t just any target in Stranger Things Season 4. People trusted her, she had the power to influence the way the town responded. By pulling her into his head and demonstrating what may become of Holly, her parents, and Hawkins, Vecna achieved a number of objectives simultaneously.To begin with, he instilled fear in the most appropriate spot: Nancy was heard by Hawkins. When she would tell people that danger is at hand, it would spread like wildfire.Second, he drove individuals to do things that are beneficial to him. When a trusted person gives a warning of doom, families may flee, get hysterical or even turn against each other and all these actions would make Hawkins weaker and easier to be broken by Vecna.Last but not the least, it is emotional cruelty. Vecna does not simply want victims, he wants to destroy the morale of the town. The idea of presenting Nancy with a future where her little sister and parents are under threat was supposed to frighten, disorient her and loosen the ties holding Hawkins together. It is a classic villain tactic, scaring one individual to cause havoc on everyone else.Hawkins goes into crisis mode View this post on Instagram Instagram PostThe moment Nancy returned from the mental lair of Vecna with a horrible vision of the future, everything accelerated. The town abruptly went into crisis mode: people panicking, families evacuating Hawkins, and with Vecna opening four gates to the Upside down, deep crevices were created all over. The group had to choose whether to keep their family in Hawkins or send them away.In the finale of Stranger Things Season 4, we see dust particles falling down from the sky like snowflakes, which only hint that the Upside Down is not just a hidden multiverse but very much part of Hawkins' reality. The stakes had gone higher than ever, which are going to be more deeply explored and excavated in Stranger Things Season 5.How Nancy’s warning set the tone for Stranger Things Season 5From the very first episode of Stranger Things Season 5 Vol 1, we see Hawkins in a mess. Part of the town is put under lockdown by the military following the disaster that occurred at the culmination of Season 4. Central to this tension is the frightening vision that Nancy had, where she saw her sister Holly, and her parents in danger. It becomes the emotional spark that propels the entire story.The vision immediately increases the stake. The danger is not a far-off menace anymore or a second Hawkins mystery. It hits home. Nancy perceives her family in danger, and this change of focus changes the mood of the season, as it is no longer about a monster that threatens the town but rather about a monster that threatens the people she loves. This renders the struggle personal, acute and unavoidable.When a Demogorgon eventually takes Holly into the Upside Down to Vecna, and Mr. and Mrs. Wheeler end up injured at the hospital, Nancy realizes that vision was indeed coming true. She tells Mike that sending them away or telling them the truth would've been the right thing to do, which would've saved her family from the current mess.This drives Nancy into making difficult decisions because she is a person who thinks logically and attempts to follow up every hint she gets. It initiates an emotional conflict that develops the first four episodes of Stranger Things Season 5 Volume 1 and provides her plot with a tangible weight and a sense of direction.For more such insights on Stranger Things Season 5, keep following SoapCentral.
