No this weeks SDF is not a girl docking with her mirror image. Instead it is Alicia and Beth the powerful twins from the manga Claymore.
For those of you who have only seen the Anime Alicia and Beth are ranked #1 and #2, and are a new type of Claymore made by the Organization in order to combat the Abyssal Ones.They have been trained to create powerful mental link between the them. This allows Alicia aka Alicia the Black to Awaken, yet still retain her humanity and revert back due to her link with her sister, Beth.
