Episode Title:
Pegasus Revealed.
Episode Description:
Chibiusa's dream of being an adult comes true when, due to an attack by PallaPalla, she artificially switches ages with Usagi, who in turn wished that she was a child so she didn't have to do "hard math problems". As Chibiusa has achieved her dream, Pegasus says that he has lost sight of hers in turn. Stating that they cannot be together if she remains an adult, Pegasus turns to leave. Not wanting to lose him, Chibiusa chooses her deep and strong friendship for Pegasus instead of her dream to be an adult, thus breaking the spell, and shares a romantic kiss with Helios, who is Pegasus' true form.
