Welcome to the story "Exist", it's a RaphxDon mpreg/turtlecest/AU sort of fanfic. Please respect as I'm experimenting writing "difficult" themes. Thank you.

Rigel's POV:

I see Mama very sick today. I knew Mama tired himself too much. I really wanted to make Mama feel better.

"Ma… Ma…"

"Rigel… Baby, you go to sleep. I'm going to be okay."

"Aunt… 'Pril…"

"Baby, April is on vacation with Uncle Casey. Don't worry, I'll be fine." I heard my Mama coughing hard. It really sounded bad.

"You go sleep, okay?"

I crawled back to bed. But the rain is making me awake. I checked Mama again. Mama seemed like he ran fast for some reason and he is very warm.

"Raph… Raph…"

I blinked. Who is that? Mama, I'm Rigel. Mama is very sick. I had to get help. I hold Mama's phone. I always play games with it. Yet sometimes, I fumbled to other buttons.

I think I went to this list of names.

"Raph" is what Mama said. Maybe he can help Mama. I scrolled downwards to these names. Mama taught me some letters like in my name. My name is like this Raph Mama talked about.

I saw a name.

Ra-pha-el.

Raphael. It's a little different from Raph. Maybe they are the same person?

I need help for my Mama.

I pressed the button and put it beside my ear. It's making sounds.

Raph's POV:

I grunted in frustration when my T-Phone rang loud. I lazily grabbed my phone and looked at the caller. My body froze and quickly pressed the button.

It's Don! It's Donnie!

"Hello, Don?! Donnie! Come back home!"

I really didn't know what words I want to say. I just need him home. But I heard nothin' followed.

"Don?"

"Ra… Raph?"

My eyes widened. The voice is not Don's! It sounded way younger.

"Wha-? Who are ya?! Why did ya have my brother's phone, kid?!"

I can hear the tense from the other line. I don't understand.

"Save… Mama."

I'm so confused. Then, I didn't hear anythin'. I lost the damn call!

I felt anger risin' in my chest again. The same feelin' I always experience. The fuse that is goin' to go off and explode. But I breathed deeply, tryin' to calm myself. I thought of Donnie smilin' at me.

After Don's disappearance, I consulted Leatherhead by the order of Master Splinter. He said I'm out of control and spiralin' into anger and depression. I learned how to minimize my anger. I don't want to fight with Donnie if he and I had the chance to talk. For a hot head like me, it's really a challenge but LH said the tip is to think of somethin' that makes me calm. For me, it's someone. His smile made me calm. His eyes washed my rage away. I like to think he had powers to tame me.

I still didn't know why that kid had Don's phone. Either way, it's a sign he or someone needs help.

Rigel's POV:

I'm waiting here under the big tree. Mama built this elevator thing so I can come out easier and play outside. It's raining hard and made me wet even though I'm under the shade.

I want Mama to be better. I need help.

"… Kid?"

It's the same big voice earlier. Finally, Raph is here! I turned around and I'm really surprised.

It's Nightwatcher!
