After much deliberation, she decided to return to Brazil to sort things out...
Tara Summer also got in touch with Emily Stone's adoptive parents, who were in Night City, so they arrived at the island that very evening.
Having seen the paternity test report, the adoptive parents believed that their daughter indeed was Morgan Benson's sister, and they agreed to let him take her back to Brazil to visit her biological parents.
Seeing the adoptive parents' reluctant expressions, Morgan Benson assured them that Emily would always be their daughter, and that he would bring her back to Night City to see them whenever he had the time.
Morgan Benson had also decided that his sister would continue using the name Emily Stone, in gratitude to her adoptive parents for their kindness in raising her.
As for the name Duoran, it could be used as a nickname that the Benson Family would use in private.
