It’s ether that her “element of laughter” is calling inside of her… or she’s just showing off her gorgeous, blue eyes.
 
It’s simply both.

They Saw The Double Rainbow, And They Know What It Means.

Twilight probably won’t get her key until the finale.
 
…and I still say it’s gonna be that journal. Just watch.

As amazing as that would be, nope.

I’m sure it will involve Trixie somehow

@PonyPon  
Guess what, you were right.
 
“Rarity” takes Manehatten  
“Rainbow” Falls  
“Pinkie” Pride  
“Twilight” Time
 
And all their keys come from a pony that gets inspired by their actions.
 
Coco: Inspired by Rarity’s generosity, she quit’s working for Suri and gives Rarity her prize, and a spool of thread.
 
Spitfire: Inspired by Rainbow’s loyalty, lets Soarin back on the team and gives Dash a medal.
 
Cheese Sandwich is interesting, he was inspired by Pinkie Pie from the very beginning to become a party pony. He gave her Boneless for reminding him what having fun was about.
 
I’m not sure about Twilight though. Since she is the main character, I don’t know how she will get her key. What does the element of Magic do to have a “rainbow eyes” moment? We can only wait…

@Bhazor
 
“Cupcakes” was right, then.

@PonyPon  
That starts another theory…
 
“Twilight Time” is when Twilight gets her key?
 
Then we have to wait later to see when AJ gets hers and see if the episode title theory is correct.

@Color Clouds  
Key episodes have the character’s name.

Theory: Every other episode one of the mane 6 gets their key. So the episode that airs two weeks from now “Filli Vanilli” will have Fluttershy getting her key. Then we have “It Ain’t Easy Being Breezies” for the episode two weeks after, but not sure if anypony is getting their key in that episode, because who knows if it’s a Fluttershy episode or someething…

It is not rainbows. Its colors of the mane 6.

With this marks Pinkie’s descent into madness and bloody cupcakes

@Background Pony #0BFF  
It also symbolizes toyeticness.

I think I can guess the meaning of the rainbow-eyes. It’s symbolizes epiphany.

Rarity: Revelation  
Dash: Resolve  
Pinkie: Recoiling in horror
 
Interesting how each reacts to the rainbows.

Rainbow Dash in pain? My destiny!

Okidoki, Toki.

Pinkie can now shoot rainbows sideways out of her eyes. Toki would be proud.

Rainbows, Darling. Rainbows.

i wonder who came up with this reoccurring rainbow vision
