Realizing she is in dire need of assistance, Ethan offers to help, in turn risking revealing his and Sutton's secret relationship. Will Emma be able to put aside her worries for Sutton and shine on the dance floor? Or will the night's series of events force her to reveal her true identity?

Although the outcome may not turn out to be what Sutton had hoped for, it does lead her to wonder what everyone around her has been hiding for all these years. Will Sutton be able to find the answer about why she and Emma were separated, or will her curiosity put her and her loved ones' lives in danger?
