Danny Phantom theory 2: What if Danny's cousin/clone Danielle wasn't really his clone?

So we all know of Danielle "Dani" she was the clone/cousin to Danny Phantom, but what if she wasn't a clone. What happen if she was really his oldest sister? In the Early days of Danny Phantom before what we got, Danny was originally going to have twin sisters but they decide to make it so he had one sister. So what if he still had a older sister and what if like Danny she was there when the parents and Vlad were making the 2nd prototype of the Ghost portal and just like Danny she step inside but she hit the button that would activate the machine it didn't grant her the Ghost DNA like it did for Danny but in stead it accidently killed her. Since the machine was still in its beta stage It probly wasn't safe for humans. Her death would of been so dramatic to the Fenton's. Knowing what had happen and wanting to continue the project Vlad would of use a machine to erase the current Fenton's memories of the daughter they lost. So years later after Danny's transformation and such Vlad took what he had left of the Fenton's dead daughter, He would take her DNA and Danny's DNA to combine them and make Danielle. He also took away the memory that the clone had of her past life and made her believe she was the cousin to the Fenton's kids.

But we know that she was the only clone to survive and we also now know that she went to explore the world and find her place, but what would happen if she could regain her true memories and return and help her true family unlock there's. (Well except for Danny cause he probly wouldn't of been born yet at the time of her death.) 

Danny Phantom Theory 1: Ember's Song explains her backstory and how she died.

Yeah! Oh!

It was, it was September

Winds blow, the dead leaves fall

To you, I did surrender

Two weeks, you didn't call

Your life goes on without me

My life, a losing game

But you should, you should not doubt me

You will remember my name

Oh, Ember, you will remember

Ember, one thing remains

Oh, Ember, so warm and tender

You will remember my name

Your heart, your heart has rendered

Your loss, now bear the shame.

Like dead trees, in cold December

Nothing but ashes remain

Oh, Ember, you will remember

Ember, one thing remains

Ember, so warm and tender

You will remember my name

Oh, woah, woah!

Ember, you will remember

Ember, one thing remains

Ember, so warm and tender

You will remember my name

Yeah! You will remember my name

So could the song talk about how Ember was in love with this dude and they had the common 5 dates then he move on and she waited for him but he never came back. This cause her to not only make this

song but take on a more punk look to show her heart was broken. But lets say she made some songs

that made her some what famous and her old lover came back to her cause she was becoming popular/

They went back being a couple and then Ember then started to loose fans to due her recent songs and this would have the dude leave again and cheated on Ember with another teen singer and this cause Ember to break and she ran off into the woods, but in the song it says 

"Your loss, now bear the shame.

Like dead trees, in cold December

Nothing but ashes remain"

This could mean 2 outcomes for Ember. For one she could of froze to death. What I mean by this

is that she ran into the woods and cried while leaning on a tree and it began to snow and since she was in her performance outfit she most likely froze to death.

My Second idea was that she lit her home on fire and sat in the burning house ready for death.

This could be why in her ghost form she has Blue Fire for hair.

Maybe someday or some way we'll find about the origins of the ghost within Danny Phantom.

Here are some Vids I found that could help the theory, also here's the music video for Ember.
