The eunuch Varys had tried convincing her to join forces with "Aegon Targaryen", who was supposedly her nephew, born of Rhaegar and Elia. Daenerys did not trust the eunuch and had great doubts about this supposed Aegon. Was he the mummer's dragon? Did that mean he was fake, or the real deal, but hidden by deception? It was also truly convenient that someone was claiming to be the rightful Targaryen heir just when she had grown dragons. Where was this Aegon when Daenerys and her brother were barely surviving as beggars in the Free Cities?
