@Scrounge  
Yeah, you did.

@BubbleBlitz45  
Called it! :D

@Scrounge  
Actually, I am an only child. So I have no idea about fighting with a sibling.

I was going to suggest a brothers version of this, bu then I realized there’s no point. Flim and Flam would win because Rumble and Thunderlane barely have any screen time, and Tirek and Scorpan, well, Scorpan never even shows up in person. And those are the only sets of brothers.
 
@BubbleBlitz45  
I think having those moments when they don’t get along helps it be sweeter when they do. And besides, if you tell me you’ve never had a fight with a sibling, I will know that you are either a filthy liar or an only child. :P

@Scrounge  
I very much agree, when Rarity doesn’t go on her dramatic bitchy moments.

@BubbleBlitz45  
I’d go so far as to say it’s adorable.

@Scrounge  
I agree with you so much! Rarity and Sweetie Belle’s relationship can be quite cute!

3 and 4, now that we’ve seen Marble and Limestone.

Definitely the Pie sisters! They’re both awesome and adorable!

1 , then 3. I would like to see more of 4.

Does 4 include Maud?

1 and 4 desperately need to be developed more.

AJ and AB.

4 or 6

tie between 2 & 3, pretty much my four favorite characters too

1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1

I love them all. But really, the two who seem to get along best are Aloe and Lotus, and Flitter and Cloudchaser. And I just can’t deny my raging pegaphilia. So it’s 6. for me, with Luna and Celestia a close second. I actually adore Applejack, Apple Bloom, Rarity, Sweetie Belle, and the rest, but I don’t really like them as sister pairs, more as individual characters.

We really need more of number 4.

3, 4, and 6

@wolfstorm56  
ditto

2

1, and they need more screen-time. 3 has a close second though.

Watching two very different people go at it is more interesting
