Applejack: Twilight, you have to go out there, face that mob and apologise for what you did!  
Twilight: I will, but if I go out, I’m afriad that they’ll get all six of us.  
Bon Bon: No we won’t, we just want Twilight Sparkle!  
Twilight: Well maybe not you, but they might take Spike!  
Spike: I’m part of the mob, Twilight!

Those are clearly humans…

“By my blood and by my death, I CURSE YOU ALL!!  
As I die, SO SHALL YOU ALL!!!”
 
 
(you better get this reference)

She turned me into a newt!  
…  
I got better.

Besides, how do we even know it’s not a one episode thing anyway?

It’s not so much Twilight getting a new form as it is Twilight achieving what’s been interpreted by the fandom as being Equestria’s equivalent to godhood.

Oh, dear gods, I remember that.

“I’m telling you people, the earth revolves around the sun!”  
“Burn her!!”

This sums up how the fandom is reacting quite well.

Emotional Detachment, in my opinion. The adorkable bookworm is moving on up in the world and you can’t stop it.

Check to see if she weighs the same as a duck!

SHE TURNED ME INTO A PARASPRITE!
 
I got better…..

Twilight Sparkle is going to die for your sins!

If you are truly the daughter of Faust, save yourself.

Has anyone read that old fanfic about the earth ponies and their anti-magic rope?

@Prince Leaf  
Oh, I gotcha  

Something about burning steaks?

@Blackie

@Blackie

FEAR NOT, TWILIGHT, THE AGATHA SHALL FREE YOU FROM MASON EXECUTION

Serves her right.

“You all do realize I can still use my horn, right?”
