Marble Pie is a shy, quiet mare that rarely speaks and almost never makes eye contact. Rainbow Dash is known for being outspoken and assertive. When Pinkie's sisters -- including Marble -- come to Ponyville for a visit, Rainbow Dash somehow gets set up on a date with Marble Pie.
Do the two have a rock solid foundation that a relationship can be built on? Or will the entire thing crash and burn?
