mommy is here sweetie belle

Rarity received wings and saved Sweetie Belle from the danger of falling! That’s what friends (and sisters) are for!

From the source:
 
Wow! Where’d you get the wings from?  
On my trip to Canterlot I met up with Princess Celestia to design her a new wardrobe. It all started with some small talk, until she asked me how you were doing.  
COOL! The Princess contracted you to work for her?! What’d you say?  
I said I was worried about you all the time. In spite of our many… squabbles- you’re the reason I keep striving to do my best. That… if anything happens to you I’d be the first to lay down everything- everything for just the smallest slimmer of hope to get you back.  
…You’re kidding, are you kidding?  
She bored into my eyes for a moment- it… felt like minutes to me. Eventually she digressed, and started talking about her own littler sister. She paused for a moment, and with some hesitation asked me what I would have done in her place when Princess Luna began to grow envious.  
What’d you say?  
I said if Sweetie Belle and I were in that position- I’d have everypony sleep during the day instead. Princess Celestia turned away and stared out the nearby window for a bit. Without averting her gaze she said I was the first pony who answered that question that way. Twilight Sparkle said she would have done exactly as I have and banish Princess Luna. Trixie would have taken away her horn and wings to be exiled, and Sunset Shimmer… would have dueled her sister for a more “permanent solution”.  
Muttering under her breath, murmurs and whisps about “turning the clock back” and “giving me a chance at becoming a star pupil of hers” filled the air around me. I caught wind of it eventually, and had to politely point out that I already had my destiny set before me. I could tell it killed her inside, but I didn’t say anything. She turned away, again muttering- this time about a “cutie mark”, and something “so powerful she herself had to cast it”. Before her eyes darted around too much I stepped her and held her in my embrace, sliding my hoof down to readjust her attention back to me. I told her that she owed me nothing- that my friend Twilight deserved to be where she is.  
So… why are you a princess now?  
I’m not. I could have been, and I gave that back to Twilight. So… she gave me these wings knowing that I deserved them.

God I love this one. And not just because I like seeing the other 5 as alicorns ;p

NOPE NOPE NOPE!

Maybe Sweetie thinks of her big sister as this.

Well worth reading the description at DA.

Best alicorn

I would actually really, really, really like it if they did something like this.
