Yep, I'm The Outcast From The Sea. (Outcast Angelfish book 3)

Aiko

The person we saw with the Hoddie earlier is in the water,sittimg carefully with both of his hands in the water. Lukas is looking at the water with slight panic. Lyla comes back up on the surface, dragging Ethan to the shore. Me and Lukas run towards her but Lukas was keeping away from Ethan, like he was afraid of him.

"Is he okay?" Lukas asks.
"He's fine.." Lyla replies.
Lukas scaredly looks at the water.
Ethan moves around a bit. Some water hits Lukas and  he gasps. Lukas gropes at his stomache and he falls down.
"Lukas, you alright?"
Lyla finishes drying Ethan off.
"Can't ... breathe.."

  The person in the hoodie gets up and walks towards us.  The water turns back to normal. Lukas slowly starts breathing again, but short breaths.
"Is everything okay here?"
It was a male voice.
He looks questionably at Lukas.
"Is HE okay?"
I turn my head to him.
"Who are you?" I ask.
"Doesn't matter, just wondering if he is okay." The guy replies.
He looks at Lukas and Ethan
"Are they hurt?" He asks
"Answer me." I say sharply.
"What's more important, my name or their life?"
"What do you want?"
"I want to help if it's possible."

Ethan sits up.
"I-Im fine.. ill just go home."
His eyes where in slight panic. He gets up and runs off.
Lyla didnt seem the slightest bit worried about it. She just gets up and leaves. I on the other hand was very confused and I decided to leave it up to her.

Lukas coughs and black mist surrounds him. The boy backs away.
"What's that mist around him?" He asks.
"I Don't know." I reply.
He kneels down next to Lukas. He looks calmly at me, then at Lukas.
He puts his hand on his chest and pushes his thumb down on it. He puts his other hand to his forehead and pushes his pinkie finger down on it.
"What are you doing?" I ask.
"Honestly, I dunno." He replies.

The boy roughly pushes his thumb down into his chest. Lukas' eyes open wide and he screams in pain.
"What the fuck are you doing?" I say.
"I don't know what I just did.. but... he's breathing properly again!"
He touches the water again and it goes pitch black.

Lukas groans.
"Nauseous... Have to-"
Lukas throws up.
The boy moves away from the water and the water immediatly turns normal.
"Are you okay?" He asks Lukas.
Lukas nods.
"Im fine.. just... feel dizzy.."
I help him get up.
"Okay.. ill take you somewhere to rest" I say to Lukas.
Lukas leans on to me, putting most of his weight on me but I manage to walk anyways. He seemed really sleepy. I take him to the apartment.
I struggle to take out my keys since I had Lukas leaning on to me but I manage anyways. I unlock the door amd suddenly realise, the guy is still there.
"Why are you following me?" I ask.
"I taught you said I had to come with you, to rest" He replies.
"I was talking to him" I say, looking at Lukas like it wasnt obvious enough.
"Oh... So I don't get to rest?" He asks me.
"Uhh.. you can.. but you didnt have to follow me to my house to do that.."
"Awesome!"
The boy walks into my house and jumps onto my couch. He grabs a pair of handcuffs and attaches himself to the couch.
"What the hell are you-"
He looks at the key and they he put it in his mouth, swallowing it. He coughs for a bit and then closes his eyes.
"Seriously, why?"
I sigh and facepalm.
"Okay, ill sleep on the floor tonight, Lukas you can have my bed."
"No.. you sleep in your bed.. I'll sleep... right..."
Lukas faceplants onto the floor.
"Here"
"You sure about that?" I ask.
I could hear a muffled "mhm"
I hand him a bucket and a pillow.
I look over at the guy. I shake him slightly.
"Wake up." I say to him.
Suddenly, my hands get surrounded by black mist and I feel dizzy and nauseous. The room spins and I fall onto the floor. After a while, I start to feel better and the dizzyness fades away, however I was still a bit nauseous.
I look up and realise,I wasnt dealing with a normal human here. I grab a knife and put it to his neck.
"Tell me who you are." I say fiercly.
He opens his eyes and they widen.
He shakes and his lip trembles.
"Wh-what are you doing?"
"Tell me who you are." I repeat.
"I--I  dont know..... What? Please.. get that knife away from me."

He shakes and his head twitches, making the knife  cut him slightly. He yelps. I slowly remove the knife.
"Tell me who you are, and I will not hurt you." I tell him.
"O-okay.. I um.."
He looks at the handcuffs.
"I'm a boy... I'm... 16 I think.. and I do not deserve to die today.."
"Name?"
"I-  Ai... Aiko.."
His handcuffs slowly start turning black.
"What are you?" I ask, not making myself sound any kinder.
"I'm.. nothing... just another human in this world as far as I know.."
I look at him suspiciously. He seemed like a nice guy.
"I won't  hurt you." I tell him.
"Should've-"
He moves his head rapidly to the side
"Bitch!"
I frown slightly.
"Is anything wrong?" I ask.
He looks down sadly as his head twitches.
"Nothing much."
"I just wanted to ask you a few questions.."

"Fucker!" He says.
"Seriously, what's wrong?" I ask.
He twitches again.
"I um.. I have tourettes."
"What?"
"Tourettes syndrome. It's um.. where you have a bunch of tics and.. you can't control them.." He explains.
"Okay." I reply.

"It's like.. the urge to tie your shoes.. or.. the urge to move your feet."
Thats a weird urge to have, but this was a syndrome so I couldnt really blame him.
"Except.. my body does it on its own. And I shout out words.. But I dont mean them-- CARROTS!-- that was unintentional.."
"Okay."
His head twitches and he makes a small whimpering sound.
"Im Jessil Oceons, but everybody just calls me Jess." I introduce myself.
"Okay.. I'm Aiko.. I'm going to kill you! I have bombs!"
His head twitches again.
"No I don't"
Aiko looks over the couch and looks at Lukas.
"Who's that?" He asks.
"That's Lukas.. let him sleep.."
"Apple pie, Apple pie. Oh okay.."
He looks at me.
"So.. is he.. FUCKING BONKERS! Sorry.. Is he like.. your boyfriend?" He asks. I was about to laugh then but I didnt.
"Yes." I reply.
"I saw you two being close at the campfire. They're going to fuck! Shit!  Fuck! Aww that's cute. He has cool hair. I like the blue dyed part. It makes him look  edgy. TRUCKERS!"
Aiko laughs.
"There arent any truckers here." He says.
I  sigh sadly.
"So you're telling me, you have no control over your words?" I ask.
"Yeah.. I can supress them... but  they have to come out some time."
"So.. did you want to handcuff  yourself?" I ask.
"It was an urge. A tic that told me so and well.. my stomache hurts like hell.. I ate the damned key.. FUCK ME"
Aiko turns red but I just ignore the last part.
"I can try breaking off the lock." I say.
"Um.. sure.."
I get my knife and slowly start cutting the metal.
"Shit!
Fuck!
Sorry.. I tic alot when i'm nervous.
Salt and pepper!
Pepper!
Salt and pepper
Pepper!"
He repeats that last part like six times.
The chain is  half broken and my hands suddenly turn black again.

I start feeling nauseous again and dizzy again.
"Uh oh." I hear Aiko
I drop the knife on the floor
"Are you okay?" Aiko asks me
" N - n  - n."
I  fall off the couch.
"Call an ambulance! 911, what is your emercency?!" Aiko shouts out.
He grabs a Phone out of his pocket and he dials 911.
"Fuck! Shit!"
He removes the Phone from his ear
"They hung up.."
I wonder why.
Aiko tries reaching over to the couch.
The black slowly fades again.
" Helicopters Carrot juice!"
I feel slightly better and I could feel the dizzyness go away.
The nausea also fades away after a short time.
"Are you okay? PIRATES!"
I take the knife from the floor.
"im fine. Ill continue breaking the chain."

"I like you! I love you" he tics again.
"I feel bad for you. Sometimes you say the wrong things at the wrong times." I tell him.
" Sometimes I think that my tics--FUCKING HELL-- are like... different people living in my head.
It's... it's fine. I can live with it... I think. SHIT! TADPOLES!"
He laughs.
"Haven't heard that one before." He says.
Aiko sighs.
"It... just doesn't feel natural.
Like... it's someone else controlling those words and not me. That's what I think of it. I believe in way too much.
Like, you could convince me that mermaids exist and I'd believe it. I already do. FUCK! My sister loves mermaids. She loves fairytales and stuff."
"You beleive in mermaids?" I ask
"Yeah... I mean... c'mon... we evolved from fish, so don't tell me--TADPOLES-- that there's not a part of people left WITH a tail."
"Didn't we evolve from Apes?" I ask
"HARRY POTTER! Yeah... but our far far far away ancestor is a fish."
" I really like Harry potter." I say quickly changing subject.

"Hey, me too! What house are you in?" He asks
" Gryfindoor pride." I reply simply.
"I'm in Gryffindor too!" He says.
Aiko smiles.
" Im partly Hufflepuff too..Mostly Gryfindoor though."
"Oh, awesome.What do you think Lukas is?He's really tired---FUCK ME HARDER! Oh geez. Here comes one."
Aiko says as he starts sneezing rapidly.
