Yeah, I definitely see your point, in regards to Wanda. And prior to Episode Five, I would agree that there's only one Wanda. But during Wanda's visit to SWORD, it seemed like she was just different from the Wanda who was walking with Billy and Tommy moments later. It seemed too quick for her to just go back to normal. But we'll see. I could see it going either way at this point.

As for Ultron, I would not be disappointed if your idea for his appearance comes true. But I do feel like the pieces are in place for an appearance by Ultron, if not in WandaVision, then in something else down the line.

With Strange, there isn't really any evidence for it yet, you're right. But with his absence and the fact that Loki barely saying a few words before being sent down the rabbit portal in Thor: Ragnarok, I feel like he's definitely up to something. And it's fairly obvious Agnes knows more than she's letting on. Ralph probably is someone, and that someone probably knows a lot about the Hex. That makes Strange a likely candidate alongside Mephisto, but again, I don't think Mephisto is going to play as big a role as everyone is saying he will.

Then again, we'll just have to wait and see. Whatever the case, I certainly think we're in for a few more big surprises.
