I might have figured out (almost) everypony’s ages · 6:16pm Sep 26th, 2021
Yep, you heard right! I did!
Let’s start from the pointers we have from each season.
Season 1 has 3 major pointers.
1) Twilight advances in her studies
I’m thinking of this like going to college at 18 years old.
2) Fluttershy & Pinkie
Probably in Bridle Gossip, I think, Fluttershy states she’s a year older than Pinkie Pie.
Seasons 2 & 3 have no pointers, but they will come in handy soon.
Season 4 has 1 pointer, an important one.
1) Rainbow’s Cake
