Vecna wants Will Byers because Will is a crucial, recurring psychic vessel and a key to Vecna's plan to merge the Upside Down with the real world, needing him to become one of twelve "perfect vessels" for his new reality, possibly to control or corrupt him as a powerful link between worlds. Will's connection to the hive mind and his unique ability to manipulate time (as seen in Season 1 when time froze around him) makes him invaluable, not someone to kill, but someone to possess or transform into a powerful minion for his ultimate apocalyptic goal.
Speaking to Variety, Stranger Things creators Ross and Matt Duffer explained that Will is channeling Vecna's powers, comparing it to “puppeteering.” “He taps into the hive mind, and then he can manipulate anything within the hive,” said Matt Duffer. “That's how he's able to manipulate the monster.
Vecna's ultimate goal in Stranger Things is to merge the Upside Down and the human world into a single, new dimension where he can rule, achieving a twisted form of unity by breaking humanity's perceived flaws through mass destruction and psychic control. He accomplishes this by killing traumatized teens to open gates, but his new plan (post-Season 4) involves using 12 specific children as "perfect vessels" to create a vast, controllable network to reshape reality, essentially turning the world into a twisted extension of the Upside Down.
He stuck one of the Upside Down's tentacles in an unconscious Will's mouth and then began pumping him full of what looks like nasty Upside Down goo. That's how Will ends up coughing up an Upside Down slug at the end of Season 1.
Vecna says why in season 5. Will was weak and an easy target and he needed to see what the limits of his powers were. He says Will was the first, but also the one who showed him what he could truly do.
Dr. Martin Brenner and the Hawkins National Laboratory faked Will Byers' death in Stranger Things Season 1 to cover up their involvement in his disappearance and the existence of the Upside Down, creating a dummy body (rubber with stuffing) and having state police plant it in the quarry to mislead the town, according to. Chief Hopper discovered the cover-up when he found the body was a fake, realizing the lab was involved.
Yes, according to the show's creators, Mike did realize that Will's "crush" in his coming-out speech referred to him, even though it wasn't explicitly stated in dialogue; his reaction shots and subsequent apology scene were designed to show he understood the depth of Will's feelings, though the payoff for their storyline was minimal in the finale.
Yes, the Demogorgon did essentially "impregnate" Will in Stranger Things Season 1 by implanting a slug-like larva into him, using his body as a host to grow and produce more creatures for the hive mind, a process that was later revealed to be part of Vecna's larger plan. Will coughed up this larva, which then hatched into a polywog (stage two of the Demogorgon life cycle), demonstrating how the Upside Down creatures reproduce and spread, as seen with Barb Holland as well.
Yes, it is canon that Will Byers has romantic feelings for Mike Wheeler; actor Noah Schnapp and the show's creators have confirmed Will's sexuality and love for Mike, building on years of subtle hints and emotional moments within the series, especially prominent in Season 4 and leading into Season 5, where Will's struggle with these feelings and coming out are central to his storyline.
The Slug-vomiting Charm (Slugulus Eructo) was a curse, that forced the victim to vomit slugs. They may also have taken on a sallow complexion as a side-effect. It was described as a green jet of light. Treacle fudge can cure the effects in a few seconds, although it will eventually wear off on its own.
Yes, Will Byers has a romantic love for his best friend Mike Wheeler, a storyline confirmed by the show's creators and actor Noah Schnapp, who revealed Will's feelings, especially in Season 4, where Will comes out as gay and expresses his long-held crush on Mike, even asking for a scene in the finale to provide a sense of closure for their dynamic.

Yes, Dart (D'Artagnan) is a baby Demogorgon, specifically an adolescent stage called a "Demodog," which Dustin Henderson found and raised in Stranger Things Season 2; he's essentially a younger, less aggressive version of the main monsters from Season 1, evolving from a pollywog-like creature into a four-legged, predatory form.
