I think Wanda's redemption should be done in a theme of love. She fell in love with Vision pretty much at first sight, in love with his soul...that of Simon Williams, and when he was back, they were inevitable

I didn't take too seriously when Wanda and Simon split during the Kang War. I took their lack of passion as confidence in each other during the crisis (can that word be used in regards to a Marvel book?) not as a fizzling of the romance.

Wanda was the anchor for Simon to come back physically, and I think he should be her anchor to return spiritually.

She may have lost her own mutant power, but she does have learned abilities of magic, so amnesiac or not, I do not think she is powerless.
