Because looking for Billy and Tommy was about getting her children back, not replacing the people she lost. Wanda literally created an entire reality where she could have a family with Vision, and she still couldn’t keep him because he wasn’t actually alive. What was she supposed to do, find another Vision and hope he’d fill the void left by the man she loved? 😭
Billy and Tommy were her children, and she knew they existed somewhere in the multiverse. But finding another Vision wouldn’t mean getting HER Vision back. He could look the same, have the same powers and even share his memories, but that doesn’t automatically make him the same person she fell in love with. Another Vision would essentially be a stranger to her, so why would she put herself through that when she already knew what losing Vision felt like?
Wanda searched the multiverse for Billy and Tommy, but never tried to find another Vision.
Considering how much he meant to her
So why didn’t she put in the same effort to look for another Vision?
