Turns out I was wrong.

@PonyPon  
Or there was never a pattern to begin with. But the whole name thing did seem a little to common to be coincidental.

@Background Pony #4C55  
More like writing pattern tossed.
 
Pity, I thought it was clever.

@Background Pony #0A24  
“Breezies” did not have Fluttershy’s name in it. It was her key episode. Headcanon sunk.

@Background Pony #6DF3  
Would you Kindly do it yourself?

Someone needs to update this and put the flower Fluttershy got from Seabreeze as the Key of Kindness.

@Background Pony #0A24  
Twilight Time is not a key episode.

@Dogman15  
The Key episodes have a character’s name in the title. The next Key episode is sure to be “Twilight Time”. The titles of the episodes about AJ and Fluttershy’s keys have not yet been revealed.

@Crowley  
Excuse me, the title is “TWILIGHT Time”. How can it not be a Key episode.

We saw Rainbow got her key in RAINBOW FALLS. What idiot missed that?

Aha! I never thought of this or made the connections between these items. I knew the mane six were each going to have their own episode where they found a key, but I thought they’d be like…keys keys. Not “magical items that represent friendship” keys. :P

@Crowley  
The episode after Twilight Time is “It Ain’t Easy Being Breezies”, and that sounds like a Fluttershy thing. The episode after THAT is “Somepony to Watch Over Me”, and that one IS an Applejack episode.

Haha, someone else noticed this too!

@PonyPon  
Yes I have. And I’m not sure she’ll get her Rainbow Item that episode…
 
a) It’s looking more like a CMC episode than a Twilight one.  
b) All the “Rainbow Item” episodes are seperated by “None-Rainbow Item” episodes.  
Bear with me…
 
Rarity Takes Manehattan = Rainbow Power given to Rarity by Coco Pommel.
 
Pinkie Apple Pie = No Rainbow Power.
 
Rainbow Falls = Rainbow Power given to Rainbow Dash by Spitfire.
 
Three’s a Crowd = No Rainbow Power.
 
Pinkie Pride = Rainbow Power given to Pinkie Pie by Cheese Sandwich.
 
Simple Ways = I estimate… probably no Rainbow Power.
 
Filli Vanilli = I estimate… Rainbow Power given to Fluttershy by the Filli Vanilli Band Members.
 
Twilight Time = I estimate… probably no Rainbow Power.
 
I’m also wagering that the episode after Twilight Time will be an Applejack episode…

So… 3 down and 3 to go…

@Crowley  
Have you taken into account what we know about Twilight Time?

@PonyPon  
I think it is. Think about it;  
So far, every “Rainbow” item has been to do with something personal that the characters love, and from someone whom they’ve shown their elements. Let me explain…
 
Rarity loves dress-making, she gets a thread from Coco Pommel for showing her that generous ponies still exist (thus giving her the courage to quit her job).  
Rainbow Dash loves the Wonderbolts, she gets a Wonderbolt badge from Spitfire for displaying Loyalty to her friends, and showing Spitfire the error of her ways.  
Pinkie Pie loves humor and making people smile, she gets a gag rubber chicken from somepony who she changed the life of (years and years ago).
 
It’s always something that the characters love, and given to them by somepony who most witnesses their “elements” first-hand. It stand to reason that Twilight would get a book (she lives in a library, and it’s her passion) and it’s from the royal sisters, who know about her proficiency in the “Magic of Friendship” (see; all those letters she sent way back when).
 
I just realised how big of a pony nerd I am now. :/

@Crowley  
I feel that’s kind of unlikely.

@Background Pony #B9DB  
Someone screencap this comment so we can all see how inevitably correct he is. Cause I think it’s the journal too.

please remember to set spoiler tags for the episodes. Especially the new ones.

@evilpresident  
I assume they’ll transform into the actual keys like the Key to Time Segments did on the classic Tom Baker Doctor Who episodes.  
@TomCatFort  
What he said.

@MadVillan  
nope, sure will be something related to the CMC, because the episode that has Twilight name in the title is “Twilight Time” and according to the summary will be a Twilight/CMC.

Twilight’s key is Spike, when she finally becomes friends with him.

Twilight’s key is the journal.

@DripDrop  
the same way a thread and a medal are a key.
