After Sam entered the Miss Teen Seattle-pageant seven and a half years after being suspended from pageantry for supposedly pushing LeAnn Carter down a flight of stairs, Sam and Ernie reunited just before the start of the talent portion of the competition. Sam did a dance routine for it, and Ernie acting as her partner--they did something that Sam referred to as "the train station routine." The performed it flawlessly, and Sam won first placei n the pageant.
