The first two Thor films were essentially rom coms and the Darcy character fit in perfectly as the wacky bff. Its nice to see she went on with her studies after she left the series!
Though Monica thinks this is all Wanda's doing, someone must have taught Ms. Maximoff how to create and control a pocket reality and reanimate a corpse with its original personality and emotions. So I'm still holding out for at least a co-villain.
I personally still think there must be. Wanda is probably doing some of it by herself but she doesn't *always* seem aware that she's in the reality, though she clearly takes steps to prevent things from going "wrong" with it.
Someone helped Wanda create this for their own plots and plans or is manipulating her. For one thing they wouldn't be "it's all Wanda" at the end of the 4th episode in the middle of the series if that was all it was and she was the only "villain" in her grief and madness.
The "for the children" still strikes me as someone wanting Wanda to create the twins to use their powers and/or get her to recreate Vision/Mind Stone - which we know from the trailers will come in to play somehow.
