Transform to some cool stallion. Like a hero in shining armor and fix her dress.
You decide that since you obviously can't just walk up to her in your default changeling form (at least, not without being squashed on sight) the best course of action for this problem is to transform into a stallion to help her. You imagine a stallion with brown fur, light-blue eyes, and a black mane/hair as you're briefly covered in green flames. You look over to your left and find a conveniently placed shared of glass on the ground next to you. You look at your reflection in it to see if you got the image right and you must say, you look like a very handsome stallion. You're about to go over to the poor mare to see if you can help when...
Suddenly remembering that the unicorn was one of the six mares who was kicking everyone's flank (you somehow had the bad luck of being the only changeling to get beat down by all six of them while the other changelings went down in one hit from one pony each), you decide to tread carefully and smoothly in the form of a handsome stallion carrying the sewing kit... and by that I mean you did what you THOUGHT ponies considered "smooth" and "handsome" but end up looking "adorkable" (endearingly awkward and clumsy) instead and somehow manage to injure yourself with the contents of the kit.
You suddenly remember that the unicorn was one of the six mares who was kicking everyone's flank back at the wedding! You remember them very well due to the fact somehow had the bad luck of being the only changeling to get beat down by all six of them (the other changelings usually went down after a few hits. Your durability always was a little higher than the average changeling's, but that just meant you got hit with things more often). You start to panic about actually helping her (you still have the needle marks from the invasion) but you stand fast decide to go and help her anyway. You made a vow to help others. remember?
You walk out of the bushes you were hiding in with smoothness and swagger (and by that we mean you walked out with what you thought was smoothness and swagger, but you actually just look silly) , but you somehow mange to trip on your own hooves and land face-first into the ground.
"OWWWWWWWWWWW!!"
Unfortunately, you also managed to fall right on top of the sewing kit, which gets you some brand new needle marks in places you'd really rather not mention. You look up to see the mare... still crying over the fabric, not noticing your pain at all. Ouch.
You quickly get up, dust off all the dirt, and painfully remove the needles before you walk (in all honesty, it's more of a limp now) over to the mare and say in your best "cool dude" voice,
"Need some help Ma'am?"
The mare looks at you with tears in her eyes and says,
"Oh yes please! You see, I was on my way to a friend's house, she lives in this forest you see, when the, WORST. POSSIBLE. THING. HAPPENED!!!" The mare screamed dramatically... right into your ears.
After making sure that your ears are still working, you ask her,
"May I ask what exactly happened?"
"This..." she holds up the dress as this continues "Once beautiful masterpiece, made by yours truly, got ripped when I had a bit of a, how do you say, tumble." She says sheepishly, rubbing the back of her head with her hoof.
Remembering that you found a sewing kit, you tell her,
"No worries. I think I can patch this up with this sewing kit here."
"Well... all right, but be careful to not ruin it more then it already is... if you could that is." She told you politely. You take out the sewing kit and begin to work on fixing the dress.
ONE PAINFUL SEWING SESSION LATER
After minutes using your blood, (literally you stabbed yourself with the needle a few times) sweat and tears you finally finish patching the dress. The mare takes the dress with her magic and begins to examine the repair job.
"Hmmmm, it could use a few touch-ups, but overall it is very well done. Thank you so much darling, is there anything I can do to repay you?"
You're about to tell her that you don't want anything and that helping her was a reward itself when you hear...
"RARITY! GET AWAY FROM THAT VARMINT!!!"
Uh oh...
What the heck do you do!
Just tell the truth that you want to help and if possible atone for my mistakes and do the pinkie promise
Suddenly, transform into a giant Prince Blueblood and bombard her with hatred.
Run off further into the clearing then let your wings out. Fly up into the air until you determine you're high enough. Hover for a time to gloat at easy eluding the orange menace. Perhaps park once self on a cloud and let out a good laugh, a natural way to release some of that tension you've been building up. Once you've settled down and are obviously out of reach the land walkers, open a dialogue. One way or another always bear this thought in mind, "The orange one's hat is glorious. It shall be mine."
RUN!!! GET OUT OF TH- oh, well, maybe if you tell them the truth, that you want to be a 'good guy', then- OH, SHE'S REALLY FAST! RUN, RUN!!!
4345901 does he/she know about the Pinkie Promise, though?
4346551 hmmm good point..... I always assumed when they change firm the changling gets residual memory
Become resigned to your fate and let the oncoming mare pummel you, and hope that maybe, MAYBE you can explain everything... or at least hope the dungeon food is ok.
That's Applejack, right?
Kiss her.
I am really enjoying this. Stories driven by the readers always go to fun places.
Also: Seeing no other way to avoid the train of pain coming your way, you do the only logical thing you can think of and grab the white unicorn. Holding her between you and your attacker, you proudly proclaim "This is my meat-shield! There are many like her, but this one's mine!"
Ah screw taking this seriously, panic and turn into an eldritch abomination and eat Applejack's hat. Why? Why not.
Passion kiss with Rarity like prince kiss a princess. Steal some love from her to increase your megic and use magic to power up your speed.....after that...RUN FOR YOUR LIFE!!!
Point in a random direction and yell "LOOK! A DISTRACTION!" Then try to fly away, but the rainbow blur from your nightmares slams into you during your escape.
As the ponies argue over what to do with you, WILD TIMBERWOLVES APPEARS!!! (cue cliffhanger ending or you accidentally taking down all the Timberwolves with your clumsiness)
Megaman zero and try to help others with my weaponry
Myself and pretend to be suspicious.
CHARLIE SHEEN AND MASSIVE AMOUNTS OF COKE!
Yo preferiría ser como Álex Mercer, tiene más potencial.
