As I've written Evangeline there are things that I've developed about her that I want to put in their own chapter. 

The casting of Eva is up in the air right now. At the moment her older self ( 20s') is Hailee Steinfeld, but I'm trying to figure out a younger (in school) Eva and an even older version (40s') of her. 

---------------

The main thing I wanted to address is her personality, as well as a piece of her background story.  

Originally I wanted Eva to be a female Sirius, but as I've written her, I see more Remus than anything else.

There will always be subtle bits of Sirius in her, she's just as reckless as him, as well as upfront and brave. 

But in a way she has always been more of a Remus,  maybe it's her blunt remarks or her no filter facial expressions. Some could say these are good traits of Sirius, but since Sirius grew up in a tight pureblood household I think he would have an easier time holding back what he feels. 

----------------------

Now I want to look at her physical appearance. The first thing that I hadn't put in the original description of Eva is her scars. 

She doesn't have many, but there is one very prominent one on her face. 

It runs on the left side from above the highest point on her eyebrow to the junction of the chin and throat. She was Harry's 'treasure' in the triwizard tournament and got the long cut from a particularly restless mermaid. Although she was ok, the scar would never fade. She doesn't think the scar is a big deal, but everyone thinks she's the coolest thing since the new firebolt. 

Her animagus form, the same as Sirius' has the long scar which is how she is identified. Her Patronus is also the same dog, it's a family thing. 

--------------------------------

There is one question I had when I was creating Eva, her name. Would it be another constelation, and if so what would it be?  

The reason her name is not a constellation is the fact that Sirius despises the rest of the Black family with unrelented hatred. He wasn't about the honor the Black family tradition by naming his daughter a star or constellation. That is something Andomedea did as well, although Nymphadora is a... odd name, it isn't a star or constellation in any list I was looking at. 

Speaking of Sirius Black, i want to finalize the means of her birth. I've read many versions of this, banned experiments, potions, spells, purebloods being about to get pregnant regardless of gender, adoption. It's all a lot to pick from I've chosen to go down the potion route. 

I might have adressed this in worlds collide but my reason for the potion route is just simply to make things easier. This would work for the spell route as well but the plot makes more sense this way. 

So in June 1980 Delores Umbridge passed a bill that would ban a certain ingredient for the male pregnancy potion as well as creating or consuming the potion, forcing them having to have the child in early 1979, that fixes the why didn't they just wait to have Eva problem. That puts Eva's birth early 1980. (In all regards Eva could have had a 1981 birthday by using the potion in may or april, but I wanted her to be older than Harry.) 

Sirius was the one to carry Eva as in this universe that lessoned the werewolf gene from either passing to Eva or being prominent. Does Eva have the werewolf gene? The answer is yes but it is dormant. She presents inhuman senses, speed, and strength, which other houses agrued she shouldn't play Quidditch because of that. But she does not turn into a raging beast once a month, which would be terrible for a one month old baby. (That does differ from the cannon version of Teddy who gets grumpy once a month.) 

The deal with Quidditch was that she could not play Chaser or Beater as her strength posed too much advantage. As Harry already had the Seeker position she went for Keeper, which she earned well. Additionally in the record of Quidditch positions Sirius is a Keeper, which poses more desire for the position for Eva. Because of that Ron who is the Keeper in the books/movies is a chaser.

Other differences

In the other set of notes for Eva, in the version where Cedric ya know, dies, she ends of with a guy named Alexei. You can forget that (If you remember that), now in the version where Cedric becomes Deadric, she ends up with Theodore Nott. 

Everything else on the other notes I am keeping cannon in this book :)
