The Forgotten -Marvel 2-

"What if I told you the reality we live in is one of many."

The dust has settled after Thanos. Lydia is left with an unpleasant new reality. Natasha is gone, and Lydia is processing the loss of her only family. Without her, Tony, or Steve, figuring out her purpose becomes a challenge.

Wanda's grief is becoming too much, and with Lydia's barriers destroyed, she becomes susceptible to Wanda's powers, and she wakes up in a new reality, one of Wanda's creation.
