So we really just gonna jump right in here with it—
The second I saw the light on his face and that goddamn projector I knew exactly what was being referenced—the S2 moment where we first learn of a the personality split that happens (aka to Will when he’s possessed)—
—that happens in associations with a missing right eye—
—and causes a “personality change?"
Looking at how many parallels there are even just in this teaser to the possession and tracking that happened with the connection between The Shadow Monster and Will in S2, including: Needles (to put Will to sleep)—
—dilated pupils, the tunnels, the possessed fall back—
—Even a sweaty (aka near heat just in case it goes south) Will being told to fight “again?”
MY guess is that Will thinks he's "spying" on Vecna, and the Party (Mike especially) thinks Will can be a "good" spy again—but Vecna is using to track the party / slowly possessing him and his friends think it’s just him being back in Hawkins spooking the hell out of him.
Especially with that “found you” at the end of the trailer?
It’s giving the exact same energy as when Will led the demodogs into the hospital and says “he made me do it, they upset him” in S2, down to Mike and Joyce being right next to him when its realized.
Especially with Will fully flashing back to how much The Shadow Monster hates fire in S2....and MIKE talking about a burn to start the trailer over Joyce's face?!
Oh yeah. Old plan no longer works energy coming in HOT.
Especially given we know the Will/One connection is strong af even end of S4, and this plan (sending people into the tunnels to burn him—aka the crawl?) is something Vecna is wise to now.
EVEN MORE SO now that we know Will is DEF feeling some type of way about passing his feelings off to El? Anything Will (and Mike in the wake of his “love” lie) plan(s) is going to backfire—and with how Vecna uses people’s emotional weaknesses against them, with full possessed technicolor to Will’s mind?
