Stuff that only few people noticed

[xLuneti 55]

Do you guys noticed something or a detail in the show that only few people catch on?

 

For me it's:

-Fluttershy should be a couple of years older than Twilight, based on the memories from when they got their cutie marks and the sizes of their bodies.

-When they got their cutie marks, the mane 6 were probably a couple of months older (in the case of twilight) and a couple of years than when the CMC got theirs
