Little bit of a curveball - this is written from Emma's POV... I don't know if I'll do this often, but figured I might as well give it a try. Enjoy!
Chapter 3: Family Union
I sat on the sofa, picking at my nails as I looked at the two figures, who gawped at me in fascination.
Finally, he entered - Cassius was taller than me, clad in a leather jacket and walked with something of a swagger. I examined his eyes, a warm and tired-looking emerald with an explosion of gold at the centre... just like mine - well, mine were brown but still.
He stopped and looked at the man and the centaur in front of me.
"Chiron, whatever it is, I swear I didn't do it." He promised, a sincere face looking at the centuar.
"Don't worry, it's not a question of what you've done." Chiron said as Cassius let out a sigh of relief.
"Thank God... because I thought this might be about Isaac being a complete and utter-" He ruffled his nest-like array of jet-black hair as he stopped, realising I was in the room.
"You remember Emma?" The man asked him, reading a bottle of wine.
"I met her a couple of hours ago, so it'd be a bit worrying if I didn't remember her..." Cassius shrugged.
"Take a seat Cassius." He did so, sitting next to me.
"What's up?" He looked at the wine-examiner in front of us. He put down the bottle and clapped his hands together.
"Well..." He scratched his ear. "This is hard to explain..." Cassius raised an eyebrow. "Chiron?" The man turned to the centaur.
"What Dionysus is trying to say is that... you are the only surviving son of Apollo."
"Right..." Cassius narrowed his eyes in confusion.
"But you are not the sole child..." He crossed his arms. Cassius rubbed his chin.
"Wait, so there's no sons but there's still kids-" He finally followed Chiron's stare - towards me. "Her?" He asked, amazed.
"Cassius, meet your half-sister." Cassius looked at me with bemusement, the cogs ins his head visibly working.
"Half-sister?" He asked slowly. I nodded, half-smiling - I only had one brother in my life, and I had to admit, I was excited to get another one. Especially one who must've known more about dad and this whole demi-god ordeal than me. "Are you serious?" He asked, very surprised.
"Well, you see, your father met Mrs. Taylor-"
"He was in love with my mother." He stated. Uh-oh...
"Someone can be in love with two people..." I tried to reason, but he stood up.
"She is not my sister!" He stated as well.
"Cassius..." Chiron began.
"I'm sorry, but she's not! Why didn't you tell me this earlier?" He half-shouted at Dionysus, who tried to search for words.
"Chiron did it." Dionysus stated, picking up wine to start examining. Cassius glared at the centaur.
"I thought you would like the surprise... it's been quite lonely for you here-"
"I've been fine here!" He shouted, shooting daggers at me. "Are you serious?" And with that and a kick of a stool holding a bottle of wine, he had left. There was a moment of silence hanging in the air as we all looked after the doorway he had departed through. Finally, we heard a door slam.
"Well, that was tense." Dionysus exhaled with a chuckle as he began to uncork a bottle.
"He's a deeply troubled boy." Chiron explained to me. "He's just a little territorial."
"A little?" Snorted Dionysus, who saw the concern on my face and went back to the wine.
"He'll calm down and see he's being unreasonable." Chiron reassured me. "Come, I'll escort you to your cabin.
In a few minutes, I was inside my cabin, where I saw Cassius sitting at the end, looking at something in his hands. I bit my lip, deciding whether or not I should talk to him. I cleared my throat in an attempt to alert him of my presence. He immediately snapped his head up to me and shoved a small piece of paper into his pocket.
"What do you want?" He snapped at me.
"I just... I wanted to talk." I said simply.
"Well I don't." He spat the words at me.
"Look I... I get how you're feeling. I mean, I have an older brother, and it was weird for us at first with us having different dads, but... I mean, we're close-"
"Just shut up alright!" He nearly yelled at me. "I came here when I was a kid - I've been training all my life, so don't think you can swoop in and replace me okay?"
"I... I didn't-"
"Just stay out of my way okay?" And with that, Cassius went to sleep.
For once, I understood what girls meant when they complained about having an older brother.
They can be real asses.
Hope you enjoyed - next chapter will be up at some point.
