Dawn had seen their whole conversation.
But she had only seen Serena's transformation into a girl with brown hair and she was standing too far away too hear clearly what Ash and Serena were discussing.
"Wh-what the helll, are you, some sort of magic girl!? How did you transform?" Dawn said in surprise...However she wasn't too surprised as she had seen a lot of supernatural stuff on her journey before."
Serena was taken aback and at a loss of words. Ash was not sure what to say either...
"Ehh...Well..." Serena started.
"Are you a Zorua?!" Dawn realized - she remembered her encounter with the Zorua, the Pokemon who could change its appearance.
"Not quite...Actually, she's a Latias. Well, she basically has the same transformation abilities as a Zorua." Ash reluctantly explained, as it was obvious that this situation could not be stalled any further.
"OK! I have an idea!" Dawn took out her Pokedex and pointed it towards Serena/Latias...
"Latias, the Eon Pokemon.
Latias is a female only species. Latias is a Pokémon with a bird-like body stylized after a plane. Its neck long neck stretches forward from its squat body. It has no legs, usually floating instead. The rear half of its body is largely red and the upper half white, with jet-plane wings high on its rear and fins on the bottom near its tail. A blue triangle marks the center of its chest, while a red mask partially covers its face. Ear-like fins sit on top of its head and its eyes are yellow. It has short, three-fingered arms with a red covering on the outer side of the lower arms. While it is not known to evolve into or from any other Pokémon, it can Mega Evolve into Mega Latias using the Latiasite. Latias is a dual-type Dragon/Psychic Legendary Pokémon.
Latias is highly sensitive to the emotions of people. If it senses any hostility, this Pokémon ruffles the feathers all over its body and cries shrilly to intimidate the foe. Latias is highly intelligent and capable of understanding human speech. It is covered with a glass-like down. The Pokémon enfolds its body with its down and refracts light to alter its appearance. They make a small herd of only several members. They rarely make contact with people or other Pokémon. They disappear if they sense enemies. It can telepathically communicate with people."
(A picture of a Latias popped up on the screen.) Dawn was amazed.
"Wow! You look so cool! I think that you should totally not disguise as a human! You look way cooler as a Pokemon-"
(WHACK) Serena/Latias slapped Dawn on her face. She was barely containing her emotions, it was evident that she was frustrated by Dawn "scanning" her with a Pokedex. Serena's face was red and it expressed anger and frustration. Dawn was shocked as her left cheek was glowing red under the shining moonlight.
"Ouch! What was that for?!" Dawn was at a loss of words.
"...Y-you! I'm not a Pokemon, for Arceus's sake! I'm a girl! Can't you see it? What if I treated you as a slave! Would you be so happy?! You just think you can go around and poke that device at me as if I'm some lousy Rattata?! Ugh-gh-gh...Uaaargh..." Serena broke down sobbing and crying in tears to her knees.
"I-I'm sorry...I never knew that you felt that way..." Dawn apologeticaly said as she also sat on her knees next to Serena/Latias and hugged her... When Serena/Latias calmed down, she explained her story to Dawn (leaving out the part about her feelings towards Ash although Dawn had seen their kiss anyways and the part about impersonating another girl), while Ash was rather annoyed by this drama, he just wanted to go back to the house and eat.
Dawn had an idea...
"Hey, Serena, listen...What do you prefer to be called?"
"Serena, of course." Serena instantly felt that Dawn was a person worthy of trust.
"So, uhh..Are you caught?"
"What?"
"Are you caught in a Pokeball?"
"N-no...Why are you asking...?"
