So, it has been a while since the show aired, but to this day, I think a lot of people don't quite understand the logistics of all that happened. Mainly, in regards to the existence of Vision and the twins.
A lot of people still think that they're "not real". What exactly counts as real might be a bit subjective, but they're not "fake" in the sense that a lot of people seem to think.
A lot of those misconceptions seem to come from the fact that in the comics, Wanda's twins are said to "not be real". This comes from the fact that their souls come from a shard of Mephisto's, and after Pandemonium comes to take those shards back, they're gone.
In the show however, as we know very well, there's no Mephisto. So how do the twins exist? According to Agatha in episode 9, the Scarlet Witch is a being capable of "Spontaneous creation". Right before, she says "Your children, Vision, this whole world you created... This is chaos magic, Wanda."
So how do the twins and Vision exist? Simple, Wanda created them. They're not fake. They're not "an illusion". In fact, it is established many times that everything inside the Hex is REAL, not an illusion. As per Monica, in episode 5:
"It's not an illusion, Wanda is rewriting reality"
"Wanda's twins are hers. Everything might look fake on the TV, but everything in there is real"
So why do they disappear without the hex? If they're real, shouldn't they stay alive? Again, Agatha explains:
"You tied your family to this twisted world, and now one can't exist without the other."
Wanda's mistake was that the creation of Vision and the twins was made a part of the same spell that created the Hex. So if she takes down the hex, she takes them down along with it.
It seems like a lot of people miss the fact that, Agatha explains the situation clearly to her, and then offers to make a deal with her: If Wanda gives her her power, she'll correct the flaws in Wanda's spell and allow her to live happily with her family.
The whole time that they're fighting and Wanda is shooting her power at her, Agatha thinks she's doing that as part of their deal. But we then learn that Agatha was lying, as she then tells Wanda: "About our deal... Once a spell is cast, it can never be changed. This world you created will always be broken."
Which also explains the criticism of "Why didn't Wanda just keep the hex at her house?". She can't. The spell can't be changed. She either keeps it as is, or undoes it. No in-between.
Now, more in regards to ScarletVision. I've seen some takes about their relationship in the show that are... Wrong, or at least questionable.
>"Wanda is having sex with an illusion of Vision/a mind-controlled Vision/forcing him to be with her"
Vision is not an illusion. He's a real person (synthezoid) with his own life and mind and free-will, exactly like the original Vision. The reason he disappears along with the hex is already explained above.
Wanda is not mind-controlling Vision, or forcing him to do anything. Because he and the twins were created inside the hex, they don't need to be mind-controlled to fit in on the sitcoms, and they're also straight-up immune to Wanda's powers as shown when she tries to make the twins sleep, and as said by the creators in many interviews.
In episode 5, there's the "You can't control me the way you do them" "Can't I?" which a lot of people misunderstand and take it as Wanda having control over Vision. But she doesn't. Her "Can't I?" is referring to what she does next: Rolling the credits, to end the episode. It doesn't affect Vision's mind at all.
It also just doesn't work, as Vision is able to stop the credits when he continues to argue with her. And as we find out next episode, even changing the decade doesn't take away Vision's memories and knowledge of there being something wrong in WestView.
>"Do Wanda and Vision have sex? Can they?"
This one is kind of a tangent, but, I've seen a couple arguments about the scene in episode 2 where they go under the covers in bed. First of all: Yes, they obviously had
sex. The implication of the scene is pretty clear. Vision makes a suggestive face to Wanda and tells her to turn off the lights, right after she turned their separate beds into a double bed.
The reason they have separate beds is that couples in actual 60's sitcoms did. Because them being in the same bed, implied, well, sex. There's just also no other way to interpret them going under the blanket and moving and turning off the lights especially after the faces they make at each other, so I'm not sure why there's even an argument about this.
And yes, the fact tha Wanda gets pregnant at the end of the episode DOES help with that. Yes, Wanda gets pregnants with her powers... But that's not the story she wants, she wants it to be as if she and Vision can just naturally have children. So, when she has sex with Vision that night, that should be the point where the twins are really "conceived."
>"But how can they have sex if Vision is a robot and doesn't have a-"
Just think about it... Vision, with his powers, can create his own clothes. Full-on outfits. His whole costume and a cape. He's able to change from that to his casual turtleneck outfit. He can even alter his whole body to look human. It's just logical that he's also able to create a penis.
Besides that, Paul Bettany and even Lizzie got asked about that and Vision's sex life a bunch of times. And every time they have said that, yes, Vision can change his density, Vision can create a penis, they do have sex somehow...
Note that, when Wanda does get pregnant, they don't question anything about how "But how can she be pregnant if we don't do that?", but rather just "How is she months pregnant in a matter of 12 hours?". It's true that Vision as a synthezoid shouldn't be able to impregnate her at all, but if Wanda got pregnant without them even having sex AT ALL, that would definetely be more of an issue rather than just how fast the pregnancy has advanced.
>"But that doesn't matter, cause Wanda's pregnancy is psychological".
No. How is it psychological if the children are actually born? I guess the logic here is that both the pregnancy and the twins she give birth to are fake, and "an illusion", but that has already been established as NOT being the case.
And then part of that comes from misunderstanding the storyline in the comics. Wanda's pregnancy was not psychological. She actually got pregnant and unlike the show had a normal 9 months pregnancy. The idea that the twins were fake originally came from them being shards of Mephisto (which was a retcon btw).
And then, when Bendis came to write House of M, he wanted to frame Wanda as being crazy and unstable. So he emphasized the idea of them not being real to make it seem like part of Wanda's mental issues, and also went with the narrative that a pregnancy and babies created through magic were inheretly not real.
But that's only the interpretation of one write in a couple stories. He also said "chaos magic" wasn't real, and then other comics dismissed that and said that it was. And then, they turned out to be real enough that they were able to be reincarnated into Wiccan and Speed. So, even in the comics, Wanda's pregnancy isn't exactly fake or psychological.
Even if you still see it that way though, the show is NOT like the comics. It has its own logic, which, to come back to the beginning, is that: Wanda's powers make her capable of "spontaneous creation". She fully created the twins and Vision as living people. She made the mistake of tying their existence into the hex, so when she undid the hex, which was a spell that ALTERED REALITY rather than created illusions, they were gone along with it.
