SWORD couldn't identify her - or whatever her modern alias is, so we still don't know if she was one of the victims pulled into this fake town or if she's involved with whoever created it. But it's been a running theme that Wanda isn't sure why there are people trapped in this town, suggesting since day one that she wasn't the villain controling everyone. Well, she was the one doing the current mind control, but the people were alraedy there before her and they were supposed to be from other places, they shouldn't have been her for her to control in the first place.
... Okay, I checked ep 4 again, SWORD finds the people's real names but they don't actually say where they come from. So the last problem is this cop in ep 4 who tells Monica that Westview doesn't exist, so the people must have come from elsewhere. Or are we throwing that line away as a red herring, like, was his "no such place" comment a side-effect or the hex ? Monica wonders if everyone outside simply has selective amnesia and Westview really did exist before everything. Jimmy does say he's been going through the phone book of the town, so maybe it did exist and it was, in fact, all Wanda, and Agatha just got pissed when she was caught in it (and she probably did live in Westview, SWORD just didn't get to her yet in the phone book), and she tracked the Scarlet Witch down...
Yeah I guess this episode was definitely closing down that door, the town existed and Wanda pulled its inhabitants in her pretend world, and Agatha broke free and got mad and started sending spies (Fietro) and traps (Sparky) to pick her brain. So it does point to her not trying to teach Wanda (yet), she's antagonizing her because from her point of view, Wanda did attack her town, and Agatha thinks she's the legendary Scarlet Witch fucking around with her town. But as she pokes around Wanda's past trying to find how she got that much power, she figures out her trauma and what she needs is therapy. That's actually real good for an anti-villain/anti-hero's introduction to the MCU (we don't know yet if she'll end up a villain or a hero).

Also ep 2 was another red herring, I was sure the weird "for the children" subplot would be someone else trying to make Wanda create babies and steal them from her, but it really was Wanda's desire to have a normal family. God damn I fell for all those hidden red herring double fakeout hook line and sinker

When Hayward brought SWORD, he didn't even know Wanda had created a new Vision out of nothing, he was only there following Monica's missing person case after Jimmy rang the alarm, until Darcy got the show up and running. At which point he decided to lie and show half the video footage, trying to weasel a way to reactivate his Vision. But everyone who was at the facility when Wanda came and left would know that it was a lie, and when he brings in White Vision, the rest should also figure it out. He probably expects to be praised for reactivating it, but I hope there will be fallout and outrage (starting with Monica) over that. Bring that shit up to the motherfucking supervisor already.

it was NOT a Weekend at Bernie's deal after all. Fake Vision (or Fision as Agatha would say) is not the real body at all. And that other piece of shit just set her up and manipulated what video he showed everyone, just to get something that could power up the actual body that he still had all along. Tracking Fision was probably because he was hoping to use it to restart the one he had.
Harsh.
We thought Wanda seeing dead Vision was just the illusion falling off and her seeing the real body for a second, but we should have known something was off when she also saw Fietro as the dead body when we knew it wasn't his real dead body, it had to be just her memory of it.

We still don't know where Fietro came from though, right ? And since he's doing his own thing with Monica, still under Agatha's control or not, there's definitely something there.
As for Agatha's "shock" when hearing Wanda might raise the dead, I don't think it was shock. She killed Sparky, resurrection is definitely what she was trying to push Wanda to do because she thought she might be capable of it. She doesn't seem to have anything against her though, seems she just wants to figure out if that's the legendary Scarlet Witch. I don't know if guiding her is her objective, she's not her enemy but she's still very aggressive, it's like she's trying to be all "I see through your lies, I figured out who you are", but we still don't know what she wants to do with that information (or why there's a legendary Scarlet Witch, probably has to do with the Nexus).

.... Oh yeah, there's still something bad going on with Westview. The cops in ep 1 said there's no Westview, just Eastview. And SWORD identified various people as real people who live elsewhere, not in Westview. So someone definitely still created Wetview as a trap, she took control of the place but she's not the one who put the people there.
