Another Child of Hades?

Explanations

'I've never heard of a demigod dream getting physical.' I heard Percy say to Nico.
'Hey guys, I'm back.' I say, ruining their conversation.
'Care to elaborate on that dream you got last night?' Asks Nico.
'Which one?' I reply, smartly.
'The second one, you know the one where we had to bring you to the infirmary?' Replies Nico.
'So I saw a conversation between a gorgon and the pit. We have a month to prepare, and the he told the gorgon to stab me.' I respond, summing up the dream.
'Ok. At least it is longer than a day.' Percy says.
'I'll ask you about the other dream tonight.' Nico states.
'Or now. What was that about?' Say Percy.
'Just a flashback from my first trip to Tartarus. And how we discovered my fatal flaw. And how I managed to get 15 demigods killed with it. And how I died.' I sum up, not wanting to read live the dream/memory.
'Ok... sorry I asked.' Percy says, not realizing it was gonna be that bad.
'Let's go train. You need practice with both swords, I think, and I need practice with one' Nico says.
'Let's go.' I say walking in the opposite direction of the training area.
'Where ya going?' Asks Percy.
'To the forest. Where else to train?'
I state firmly.
We all decided to train in the forest, since it was a more hands on training.
After killing lots of enemies, t was time for lunch. Nico and I went to the Hades table, and Percy went to the Posideon table. I saw a kid at the Zeus table, and told Nico I was gonna go say hi. He nodded in response.
'Hey, I'm Crystal.' I say, sitting at the Zeus table.
'Jason, son of Jupiter.'
'Cool. I'm daughter of Hades.'
'Shouldn't you be sitting with Nico, then?' He asks.
'I can technically sit at any Big three table I chose. I was just coming to say hi, and introduce myself, since I hadn't seen you around since I arrived.' I say.
'How can you sit at any of the Big Three tables?' He asks.
'I'm the daughter of Hades, blessed by Zeus and Posideon.' I state.
'Cool, how?'
'I did huge favor for them, and that was how they repaid me.' I tell him.
'I'm gonna go back to my brother if that is okay with you?' I ask politely.
'Sure, have fun.'
With that I walk away, and go sit with Nico to enjoy my lunch.
