There is no official "The Devil Wears Prada 2" movie. However, based on your question, it seems you might be referring to the lack of a sequel to the 2006 film "The Devil Wears Prada" starring Meryl Streep and Anne Hathaway.
If your question is about the ending of the original movie, Miranda Priestly (played by Meryl Streep) and Andy Sachs (played by Anne Hathaway) do share a moment at the end of the film where Miranda seems to acknowledge Andy's growth and maturity as an assistant. However, it's not clear if Miranda specifically remembers Andy after Andy has left her job at Runway magazine. The ending scene does leave room for interpretation.
In the book by Lauren Weisberger, the sequel "The Devil Wears Prada: The Movie Novelization" and a companion book "The Devil Wears Prada: On Her Own Ground" also provide insight into Miranda's perspective.
