Interesting. Yes - Tumblr Posts

Someone noticed (here) that March 29, Billy's birthday, is also the day the Cali crew is back in Hawkins.

So, I'm thinking. We see the name Billy as Max is reading the letter, but the name William when she is in the Vecna vision. That could just mean different timelines, or maybe it's also a hint that the theory that Will is in a Vecna vision at the end of S4 is correct (here)

Maybe on March 29 Vecna goes into William's mind and what he sees from the moment he touches his neck is a vision (everything else is real) The end credit song, Spellbound, is definitely an interesting choice...

I would love it if S4 starts with a flashback of El in the lab, and ends with Will in a vision. Also, we know that S5 starts with a UD flashback, so:

4x01 -> lab flashback -> then El's letter, in which she lies about her life in Lenora

5x01 -> UD flashback -> then a vision, which is also a lie?

What would Vecna show Will? Maybe the day at Rink-o-mania. But I think this would be different from El's letter. This time we would see the truth, twisted by Vecna, like the truth about Max wishing her brother to die. Maybe Vecna would tell Will that he is jealous, and that the reason he didn't help El is that, deep down, he wants her to suffer.

Well, Will is jealous, but that's normal. It doesn't mean that he's cruel or doesn't love his sister. We see that in the van scene and in 4x09.

And how could Vecna show Will that he is jealous and wants to hurt his sister? Maybe by making him be the one who throws the milkshake on her dress.

Remember the BTS photo of Noah at Rink-o-mania in his 4x09 outfit? The boy behind him and Millie is the actor who plays Jake, or his double. Jake is the one who throws the milkshake on El's dress. Jake has a bowl cut and kinda resembles Will.

So, maybe Noah was wearing his 4x09 here because this is the vision scene, and this time he's the one who humiliates El.

I could be wrong, but I think this would be a very interesting parallel with the beginning of S4. And a way to make Will more vulnerable
