So basicly Twilight got splitted into two people.

You forgot this line here that is in the version on Fan Fiction.
["Too late," Trixie smirked. "Trixie quits, and furthermore...you have been talking to a shadow clone since Trixie had seen the fire."]

I'd like to point out that, while Belle Ami does indeed mean what you say it means, it is grammatically incorrect. "Belle" is a feminine adjective while "Ami" is a masculine noun, so putting those two together just doesn't work. "Bel Ami" and "Belle Amie" would be the grammatically correct versions, and since Belle is obviously female, I'd go with the latter. Just throwing my inner grammar Nazi's two cents out there.

Okay, since when did Trixie become BUCKING AMAZING?!?

Brava, Trixie, Brava! Twilight would be very proud!

Just started reading this... And I have to say, this one's good.
Also, I found something strangely heartwarming in your Checkers.

The sadness of twilight's passing and reveal of a new evil looms over the nation along but it also brought new hope in the face of a new yet familiar looking friend .

Just dropping a comment to thank you for introducing me to that Twilight Sparkle orchestral suite music that you link to when Belle Amie first appears, I can't stop listening to it now.
