(Can become Major au considering how one's actions can change events)

I'm confused... Why wouldn't things change?

I think you need to practice more at breaking up your run-on sentences. For example, you wrote:
"Stay back i can handle it" Henry said as he stood up fighting through the pain and warm sensation "Doctor am i free to move around" Henry asked causing all within the room to look at him in a mixture of shock and worry.
The paragraph would flow more smoothly as follows:
"Stay back! I can handle it," Henry insisted. He stood, fighting through the odd combination of agonizing pain and comforting warmth before looking up. "Doctor? Am I free to move around?" Every pony within earshot looked at him with a mixture of shock and worry.
Things to do to improve your writing. 1) Insert punctuation to break up the sentences and place emphasis on particular lines of dialogue. 2) Capitalize the First Person Singular pronoun, I. 3) Trim out repetitive or unnecessary words.
Okay, that said you have the beginnings of an interesting story. Don't let it be dragged down by poor syntax and grammar. And for heaven's sake, keep working at it.

Interesting, but you really need an editor.

Yeah. I sadly don't know if that is going to be easy. Still I do hope I find somepony.

I wish you luck with it. Looking forward to the next chapter regardless.

I don't know just thought I'd have to add that to info just incase and as a little foreshadowing.

I will do my best and I put your pointers as a sticky note on my screen.

Gee... and here I thought sticky notes were only used to cover up the naughty bits. LOL. Work at it and the skill will come. And keep reading. The more you read the good stuff, the easier it is to see how it's done.

"I understand dear sister but without any suspects we cannot act and our first priority must be to ensure the safety of our ponies and family. Not to go looking through our nephew his list of enemies and transgressions to see who could get the poison."Celestia answered kindly as she tries to calm her sister.

im assuming that meant to be hit list

always liked this kind of story but they always seem to end up abandoned, hope you do plenty more it good so far

Je interesting, this story got me intrigue, and this is a subject that is not that common in the fan base, but I'm happy to see more of them popping out.
Great start, I can't wait to see what else you have in store, and who knows? Maybe if an idea pops up, maybe I might PM you message, about referring something here in my own story. Je 'the club of the reformed princes'. That sounds like fun

Also, you at times say that Blueblood was the princesses cousins, or nephew. Which one is he?

Great start so far but holy crap ease off the run-on sentences
