“Look, I’d never say this to their face… but Celestial and Luna aren’t exactly spring chickens.”

A pony Knight! Yeeeessss!!!!

Twilight, you know age spells exist per Magic Duel, and a pony as intelligent as you’re supposed to be wouldn’t put it beyond the realm of possibility there’s other means. Nightmare Moon didn’t look old, for the first of the villains, so this dialogue is completely nonsensical.
 
Hell, the CMC both aged themselves up and back down with a magical wish, and she was there for it, so this looks even stupider.
 
If anything, she should be asking “how are you looking so young,” rather than being skeptical.

I mean I don’t think so in this case. I feel like this is probably foreshadowing that they actually aren’t 1000 yrs old but either way it does make twilight look a lil foolish heh

@CORDZ2000  
More like the writers forgetting the lore…as usual.

Twilight forgetting her series lore bruh

@Starswirl  
Mares, stallions, a centaur, a draconequs, a changeling, probably at least one dragon.

… Princess Twilight?
 
You are… aware you know several mares over a thousand years old?
 
I… I don’t know what to say to that.
