I kinda felt like she did violet a favor, she wished violet to be truly happy, violet wish for her own happiness and dahye is already happy in violet's body, so something like their genuine wishes overlapped, as shannon's body can't contain a soul dahye's soul was sent back and violet returned to her own...just my hypothesis/opinion tho ╮(￣▽￣)╭
