On the first day, they didn't so much as see each other. But Mariko knew he was a silent presence on the island.
As the second day went by, there was a new shell on her side, nothing like those that usually washed up on the shore. But she hardly batted an eye towards it, snout high in the air. With a flick of the tail, she sent it flying towards the ocean, tending the letters she had yet to read.
With the third day setting on the horizon, a conch drifted to the shoreline as she caught a glimpse of feathers diving beneath the waves.
She clenched her teeth. He was always like this. He was never good with words when he wrestled with his emotions. She could sense it beneath the surface, almost like the bubbling volcanoes she spotted underwater.
Hot, wanting to erupt, but he held his tongue and left her own with no one to talk to but her Chatot friend.
Now she felt that same emotion twisting in her gut until she couldn't hold it in anymore.
"Dummy, Raiden!" She shouted at the shoreline.
No response. Not so much as a ripple beneath the tides as they gently lapped against the shore.
Her expression grew forlorn. "What did I do wrong…"
A week had passed and she found herself no closer to an answer. Mariko had gathered her letters in her arms, wobbly on her feet. As much as she enjoyed her human form, she often found herself stumbling in the sand after prolonged periods, her legs feeling jelly.
"I can do this…," she muttered under her breath. Her breath hitched as she made a misstep and lost her footing. Squeezing her eyes shut, she clutched letters tightly to her chest.
Only for her fall to be cushioned by the sensation of feathers.
"Be careful," his worried voice reached her ears.
Her eyes flew open, meeting a familiar pink. "Brother!" She squealed, letters forgotten as she wrapped her arms around his neck.
An undignified squeak from the Lugia as he wrenched back, Mariko dangling in the air as she giggled. "Sister, please," he said in a panicked voice. "Your letters."
She gasped, letting go as she landed to stumble on her feet. As she quickly leaned down to pick up the scattered letters, a shimmering of light caught her eye. Raiden assumed his own human form, kneeling down to help.
His brows knitted together in a line of worry, his eyes planted on the ground. She frowned slightly, hating the silence between them. It was… awkward, uncomfortable. Their hands met on the last letter left, his still slightly damp but he quickly withdrew as if she had scalded him.
Frowning, she sat up, truly looked at him. His hair was windswept, as if he had just come rushing from the ocean, water dripping from his bangs. Again he kept his gaze away from her, extending the letters to her.
"Raiden." Her frown deepened as she watched him flinch. "Can we sit down and talk for a moment?"
He straightened up with a soft inhale. "Yes."
That formal tone. She bristled, but she followed him to their palm tree they liked to rest under. It was slightly bent at a weird angle. A slight flush tinged her cheeks as she remembered rubbing against it much too hard to get an itch along her back.
As the sounds of their laughter from days past replayed in her ears, she didn't notice Raiden had taken his spot beneath the shade, arms folded as he looked at her expectantly.
Clearing her throat, she sat down, setting a slight distance between them.
Again, that feeling unsettled her. She fiddled with the letters in her lap, unsure how to even begin.
"I'm sorry." They said together, facing each other. Surprise broke across their face as they quickly looked away.
Then… laughter started to bubble from within. They couldn't stay mad at each other for too long. All they had was each other.
"Brother. I'm sorry if I did something to hurt you." She almost crumbled the letters in her hands. "I will try to be more mindful."
He shook his head. "It's not your fault."
"Can I ask about Father? I… I do not have a good memory of what he is like? She asked.
All she could remember was seeing her small reflection in very old but kind eyes. All else was a blur, other than the haunting sound of a familiar song that felt so much like home to her. The same song she and Raiden would sing on occasion, hoping he would somehow find them. It was like a ritual at the start of their journey.
Only that ritual became less of a habit, an afterthought until after their last trip.
A crease formed at the corner of her eyes. She remembered the determination shining bright in her brother's eyes. Now, they seemed to have lost their light as he spoke, "What do you want to know?"
It was not what she expected to hear, and now he was waiting, a pregnant pause in the air. "Well," she stammered. "Why do you want to be like Father so much? Sometimes you hurt yourself, and I don't get it."
"Maybe your brother is stupid," he chuckled.
"I think my brother is smart," she corrected him, swatting his shoulder. "But he does stupid things. I thought it was a male thing. Now I think it is only something Raiden does."
His brows furrowed with confusion. "Aren't your brother and Raiden the same?"
"No," she shook her head. "He has stopped smiling since we got here. He changed since we got to this island. Maybe we should leave. He can go back to how he used to be."
A smile broke across his face. "You wouldn't be the first to say that." He looked away. "I guess I am like that," he muttered.
"Is it something Father used to do?"
Raiden exhaled, looking towards the sky. "He always looked out for us. All of us. I want to be just like him. No matter what it takes."
Remembering the way his throat was bruised, she frowned deeply. Always Raiden pushed himself to the limit. She bit down on her lip nervously. What if he goes too far? A worry she didn't dare voice.
"Then I want to be like Mother."
His smile faltered; a strange, indecipherable emotion registered in his features. "Have you thought about not being like her?"
A flicker of darkness before he smothered it. "You're prettier than she'll ever be," he nearly growled.
A look of hesitation from Mariko. "I don't think I am."
Raiden shot his feet causing her to recoil. "What made you think otherwise?! Was it those letters!? I told you not to-"
"It's not that, brother. I don't have her… shine." She didn't know how else to describe it. A light within… but distorted. She nursed her lip as she dwelled on it. A light she very much lacked.
"Shine?" He repeated, anger rising in his tone. "Is that what you think she has?"
"What you saw… What you got is something I've never gotten from her." For the first time in a while, she saw his expression become twisted, as a knife plunged itself deep. She felt the pain as if it was her own as his expression became vulnerable. "You don't get it."
Raiden had already dived into the ocean before she could finish.
"Raiden!" She cried out, her calls unanswered once again.
