Dana Tan es la novia de Terry McGinnis desde hace mucho tiempo, y posteriormente su prometida.
Terry and Dana began dating when they both attended Hamilton Hill High School. Her father disapproved of the relationship because of Terry's checkered background, but Terry worked hard to prove his worth. Their relationship was a close one; when he had her drop him off at Wayne Manor, she expressed concern about leaving him alone in the middle of nowhere, and he responded with the same tenderness.
