"Are you caught in a Pokeball?"

"N-no...Why are you asking...?"

-"Ermmm...Hey, it seems you two are really getting along? It's just that...I'm really hungry right now...I'll go eat." Ash said to Dawn and Serena.

"Ok." Dawn said and nodded. Serena wasn't sure what to say.

Ash went back to the house.

Dawn said, "Hey, Serena. wait"

Serena felt really awkward since Ash left. She didn't know what Dawn wanted to ask her...

"I'll cut straight to business." Dawn said. "If I get it right, you want to be Ash's girlfriend, right?"

"Well, yeah.." Serena meekly responded, avoiding eye contact.

"So...Why don't you just ask Ash to catch you as a Pokemon? He knows that you're a Latias. So you could bond with him."

Serena actually never thought of this..But...

"Well, actually, Ash takes only Pikachu out of all his possessed Pokemon to a new region so there wouldn't be any point in doing that..." Serena asked after keeping silent for a while...

"Well, you'd still belong to him. Isn't that what you want?"

"Dawn...Your name's Dawn, right?"

"Yeah."

"You see...I...I don't want to be confined to a Pokeball...I know this might sound ridiculous, but I don't want to be a Pokemon. I just want to be a human girl. I've been on both sides. And I've chosen who I want to be. I just...feel like a human...and I've lived as one for such a long time at this point...Please, Dawn , I beg you...Don't tell anyone about my identity." Serena looked like she was about to cry.

"Hmmm...Ok. But, under one condition."

"W-what?" Serena nervously asked.

"Promise me that we'll share Ash between the two of us - if you ever get to form a relationship with him."

"Eh?!" Serena wasn't expecting this. (How did Dawn even imagine this to work out?) Serena thought.

"Do you agree to my condition?" Dawn asked calmly.

Serena broke into cold sweat. She surely never planned to share Ash...However, she realized that if her undercover would be gone, she'd have no chance as a Latias...Serena hoped that it would work out somehow...Right now she needed to keep confidential - that was the most important thing to do.

"I...promise...But...why?"

"I...actually...I like Ash too." Dawn gulped. It was clear that saying this was difficult for her to admit. But she decided to be honest - at least now. "But...You know how dense he can be. I...think I know what to do...But first, tell me, what are you planning to do? How do you want to achieve progress in your relationship with Ash? I'm pretty sure he wasn't really impressed - neither by your kiss, nor by your confession. Actually, this was quite expectable. From what I understand, you've travelled with Ash across a whole region - just like me. You should've known better than to throw yourself at him so easily...It's not really something a person like him can appreciate... So, what're you gonna do?"

"If only I knew..."Serena said, lowering her eyes.

"The answer's obvious, isn't it?" Dawn asked, mischievously smiling and tilting her head to the side. "How do you make a person like another person?"

"I wish I knew the answer..." Serena mumbled.

"Ok, let me rephrase that. How do you make a Pokemon like another Pokemon?" Dawn asked, obviously implying something.

"Well,..." Serena suddenly realized something and looked right into Dawn's eyes while speaking in a shaking voice. "Y-you're not t-talking about what I think you're talking about, r-right?"

"Yes, I am." Dawn shrugged in self-confidence, looking straight into Serena's eye with a challenge.

"B-but-"

"But what? What're you going to do? Throw yourself at Ash again? At best, he'll just feel uncomfortable with you. At worst, he'll just start avoiding you. I'm pretty sure you already know how dense he is. If you plan to wait until he responds to your feelings...Well, you're going to wait forever."

Serena had nothing to answer..."D-dawn...I can't-"

"Whatever. I'm going back to the house." Dawn said just as calmly, turning around and walking away. Dawn had made exactly ten steps before Serena said at her back.

"-Wait! Dawn! I...I t-think we could...discuss...y-your proposition."

(I knew she'd agree) Dawn thought in excitement, smiling.

Ok ! Responses to reviews!

jurassicdinodrew - I don't really think Mew fits into this story. At most as a cameo. Sorry.

Marshall Lee the Espeon King - Isn't that the whole point of betrayal stories though? It's a fairly well established sub-genre in the Pokemon Fandom with its own rules, and explicit character emotion display is essential to any betrayal story.

Guest - Ok I will

Temporal King - Dawn will be part of the harem

shadowkiller168 - I'll try to make it believable and as non-cliche as possible

GuardMewtwo - I'll try to be original but I can't promise

LorekeeperSam - Yeah Serena being Latias in disguise is one of my old headcanons

The Shining Fury - It's not clear yet. But Latias probably will be caught in a Pokeball. But I won't say who'll do it))).

If a Pokemon and a human had a child I think the child would be a human with Pokemon abilities. Well, I think that makes sense. I'm always open to discussion, though.

R0ck3tFiRe - Dawn won't betray Ash. Neither will Serena.
