Wanda pondered over the possibility of an outside force causing the issue. It seemed more likely that Billy was the cause, but what if it had been someone else? Her mind wandered to Loki. He had tried to manipulate her, hoping to make her question her sanity, but she didn't recall him ever using Tommy to do it. Had that been the case with Billy as well? She frowned at the thought that her lover could have been manipulating her son. She wouldn't put it past him to do so, especially during that time. He thought of and treated her far differently then than he did now. Still, even with the possibility that he had manipulated her son, what would he gain from erasing Billy's existence from everyone's memories?
She hated to say it, but it made more sense that Billy would have inadvertently erased himself than someone like Loki doing it.
"You may not think you have that power, but it is highly possible," she finally said after thinking long and hard over the situation. "Just because you may not be able to pull off such a feat consciously doesn't mean it is impossible." Wanda never dreamed she had the kind of power to create pockets of reality, but she did. "And if your abilities are anything like mine - and I believe they are - they are tied to your emotions. Do you remember any kind of highly emotional event that may had caused your powers flare?"
