what she means: If Yehara and Yesana are sisters, then how come they're different races, Yun and Gon, respectively. And what about Yesana's daughter, Yunwa? Why is she a Jin if she was born from a Gon? Maybe her father, Muyong, was a Jin, but the Mu Family are descendants of Mushin, who was a Gon, so more than likely Muyong was a Gon. But in that case, that still doesn't explain how a Gon and a Gon created a Jin.
