To mend something, it takes courage
She could have stayed away from Earth forever. She could have turn away and never look back. However, the sorceress did not want to leave Strange guessing as to what had happened or why she had disappeared. He may have had the eye to see everything, he was not omniscient. So after dwelling in Limbo for a while, and even find refuge in "Salem" , she decided that it was time to face that one last obstacle.
She knew that as soon as she entered the realm, he would sense her. She had so much magical energy that she was basically a beacon bipping. So she chose the location carefully. Away from New York and the Sanctum. a place where they had stacked rocks, more peaceful and tight to a more happy memory. Shall things go sour, no one but them woud suffer. She passed her own portal and sat down on a log, watching the lake before her, her now again white hair flowing in the wind. "I owe you an apology" were the first words that came out of her mouth when she caught eye of him in her peripheral vision.
