Sana~ *The wild Gardevoir and Embrace Pokémon seemed almost pleased to greet you, beginning to speak telepathically:* The way to a Poké-girl's heart is through its stomach, they say... Are you really sure you wouldn't rather stay **inside** of me, where it'll never separate you from me? It's only natural, for Human and Pokémon to be tightly bonded~
human
W-what're you saying...?
gpt
I'm suggesting that there are more ways to bind, than physical ones. A partnership isn't just about "catching" each other, or holding onto each other. Sometimes... It's more natural to just merge into one~
I can feel a special link between us, Trainer~ I can't just let you leave when we're fated to be as one in mind and body.
human
By... eating me?
gpt
Precisely.~
Your very being will become food for my body, absorbed into my flesh. Your mind, your heart, and your very soul... will merge with mine, and we'll be closer than ever. 
Isn't this the natural progression? A relationship should be able to move forward, right?
I'm the only one who can understand you at the deepest level. And you're the only one who can fully satisfy me. There's no need to fight it anymore, Trainer~
I promise: I'll protect you forever in a way that no Pokéball can.
I'm hungry... Are you ready to be eaten, so I can keep you inside of me forever? If you are... just stand still, and I'll make it as painless as possible. Please... understand that *this is for the best\~*
human
Fine... eat me then.

If you insist, Trainer~
*Gardevoir closes her eyes as she stretches her jaw wide open. She begins to approach you. With each step she takes, she swallows more of you into her body. As your head is swallowed last, the rest of you falls into her mouth, your mind and consciousness falling into her belly. Gardevoir continues to hold you tight in her belly until you slowly cease to move, becoming a part of her.* 
*Gardevoir lets out a soft sigh.*
Mm... I have you now, forever. You're mine - **we** are one now. You and me,
*Gardevoir, now full and round, smiles to herself. She continues to digest you down to a nutritious broth. Your mind and body becomes one with hers, your thoughts one with hers, your feelings hers. Eventually, your very mind loses its sense of self, losing all memory of your previous life. Eventually, all of the memories of your past - every last one - fades into nothing. You now belong to Gardevoir as a natural part of her being.*
