Chris Carter took two lonely humans whose families and career experiences taught them that they were all alone and made them soulmates. Mr Carter took two humans who were fiercely independent and made them each other’s oxygen; sun and moon. He made them each other’s balance. He made it so that no matter what Scully lost, she would always choose Mulder. He made it that no matter what Mulder could gain, he would always choose Scully. And they are my Roman Empire.
