Another Child of Hades?

Meeting Them

It was poring rain on an average Monday Evening. All the sudden the rain stops mid-air.
'Odd.' I say to myself. I know I'm not doing this, who is?
A group of Teens appear. 3 boys and a girl. One boy was a saytr? Haven't seen those in a while. The girl had grey eyes, one boy had sea green eyes, the other had black eyes.
I hid behind a tomb stone, wondering who they were and what they wanted. Luckily my death horse, as I like to call him, even though I named him Bones, made his horse noise.
Black eyes and Sea Green eyes gasp.
I hear my horse say, 'my lords.'
I give him a questioning look.
'Your my master and lord and they are my lords, because of their parentage.' Is what he replies.
'Ok, whose what?'
'The boy with sea green eyes is the son of Posideon. Black Eyes is the son of Hades.'
'So I have a brother?'
'It appears so.'
'Hello?' Asks the Saytr.
'Anyone here?' asks the girl.

"GO AWAY!" I shout.

'We just want to bring you somewhere safe.' Says the Saytr.
'Where?' I ask, already knowing the answer.
'A camp, called Camp Half Blood.' Replies the son of Posideon.
'I'm listening' I reply, missing camp.
'Can you come out, so we can properly introduce each other?'
I slowly step out from behind the tombstone.
'What are your names?' I ask.
'Nico di Angelo'
'Percy Jackson'
'Annabeth Chase'
'Grover Underwood.'
'Ok, I'm Crystal Rotoli.'
'Why are you in a graveyard?'
'Follow me and I'll show you.'
I say, walking towards my home for the past 61 years, yes I died at 12.
I stop at my tomb stone.
'Why did ya stop?' Asks Grover.
I simple point to the monument with my name on it.
They all gasp.
'Are you a free spirit?' Asks Nico.
'No, I died, but didn't. I woke up here, in this monument thing, that had a bed and a kitchen and a bathroom. Whoever buried me knew I'd wake up somehow.'
'Huh.' Replies Nico.
'So how old are you?' Asks Annabeth, noticing the date on the plaque.
'Technically I'm 73. I stopped aging when I died, and age really slow.' I reply, knowing I can trust them.
'Kind of like you, right Nico?'
'What?'
'I'm technically over 70 years old. I was trapped in the Lotus Hotel.'
'Ok.' I reply, knowing what that means.
'You already know what that means?'
Asks Nico.
'Yep. I actually already know about demigods, and the Greek myths being real, and all that.' I inform them.
'So whose your parent?' Asks Annabeth.
'Hades. With extra powers, but I'll wait to tell you.'
'Everyone falls silent.
'Roooaaaarrrrr'
Crap. I think.
