I don't agree with water

Our group continued through the forest, with Pinkie Pie in the lead and the rest of us following single-file. I took up the rear again, staring at Pinkie. She was jumping for some reason, I caught sight of her every time she appeared above the other mare's heads. They were still giggling, to my confusion, it wasn't even humorous, why did they even laugh in the first place?

I stopped as soon as Fluttershy, who was in front of me, walked into the others as they had stopped as well. They all craned their necks around to look for an explanation as to why Pinkie had stopped, I took the initiative and simply walked up beside the group. My eyebrows drooped in worry when I saw the roiling water.

Oh dear, rain I can handle, but this? I won't survive 2 seconds! "How are we going to cross this!" Right after Pinkie had said that, a distressed wailing sound was heard from up the river. To me, the sound was unidentifiable, "Huh?" Pinkie and the girls waked up the the bushes that hid the upper parts of the river and peered through as the wailing continued. I stayed back and inspected the river, looking for the driest route across. Thus far, it seemed futile.

After a few moments, and a lot of calculations, I had deduced it was impossible to get across without setting hoof in the water. I sighed and decided to check in with the others. The moment I stepped through the bushes, I was assaulted with shrieks of pure happiness, "Ooo-hoo-hoo-hoo-hoo! My moustache! How wonderful!" I stared at the sea serpent's mismatched moustache, staring at the purple curled part in particular.

"You look smashing!" I turned to Rarity, immediately noticing her tail, which had been cut off.

"Oh, Rarity, your beautiful tail!" Protested Twilight, who had walked up behind the white unicorn.

"Oh, it's fine my dear, short tails are in this season," replied Rarity as she turned to face Twilight, "Besides, I-it'll grow back," she said, waggling her tail as if to emphasise the point.

"So would the moustache," muttered Rainbow to Twilight, who was smiling at the time, she gasped however when she noticed the river.

"Look! We can cross now!" She said as she began walking through the water.

"Wait, girls, I can't-" I was interrupted when Twilight was lifted out of the water by the sea serpent's tail.

"Allow me," he said before sub urging back into the water, his tail creating stepping stones across the river.

Well, that works. I walked up to the side of the river and waited as the others began crossing. Once Fluttershy had gotten off the first part of the serpent's tail, I jumped. The instant I landed, the sea serpent's tail shook and the part I was standing on visibly struggled. Oh dear. "Girls I think we should hurry it along!" They had already noticed however and had sped up the pace, only Fluttershy was left on the Serpent's tail.

I readied the hydraulics in my legs so I could jump instantly, I took off jumping across the serpent's tail as it collapsed into the water behind me. Once I was on solid ground, I turned back to the river, "Sorry!" I apologised, I turned back to see that everyone, except Fluttershy, had their mouth agape. "What?" I asked innocently.

"Just how much do you weigh!" Rainbow blurted out, rewarding her annoyed looks from Twilight and Rarity.

"Uh, well, I am heavy for somepony my size..." I started, looking for some sort of explanation.

"Heavy enough that a sea serpent can't lift!" This again earned Rainbow annoyed stares.

"We can sort this out later, right now we have business to attend to," Applejack piped up.

"She's right, let's go." Twilight agreed, she turned and led the group onward through the forest.

We continued through the forest with. Twilight in the lead. I decided not to stay at the back this time as I'd gathered all the information I could about the forest. The trees started to part and through it I saw a clearing, I smiled as Twilight gasped, "There it is! The ruins that hold the elements of Harmony, we made it!" Before running straight towards the castle ruins with the others following.

"Twilight! Wait for us!" I stopped upon noticing the rope bridge however, my eyes widening.

"We're almost there!"

"Twilight, stop!" Too late, Twilight skidded before the edge and ended up with her forelegs scrambling for a grip while she was held only by her hind legs. I went to go grab her, only for Rainbow Dash to beat me to it.

"What's with you and falling off cliffs today?" She said as she pulled Twilight away from the cliff by her tail. I walked up to the edge with the others, we stared off through the fog to the other side of the abyss.

"Now what?" Pinkie stated, Rainbow Dash answered with a "Duh" and ruffled her feathers in Pinkie's vision before diving off the cliff as Pinkie replied, "Oh yeah,"

I watched as she dashed down into the fog and appeared halfway across the abyss carrying the ropes of the bridge towards the other side, she twisted the ropes around the log. As she did so, I felt another magical fluctuation, this one stronger than all the rest, so strong in fact that I actually saw a purple aura dash past Rainbow's legs. She must have seen it too, because she reared up and challenged whoever was in the fog, it was barely audible however, forcing me to enhance my hearing, "Show yourself!" I heard her yell into the fog.

The scene was quiet for a moment, till out of the fog echoed a voice. It was barely audible even with enhanced hearing, "We've been eagerly awaiting the arrival of the best flier in Equestria,"

To which Rainbow replied ignorantly, "Who?"

The voice nearly chuckled, "Why, you of course!"

"Really? I mean, oh yeah! Me! Hey, uh, you wouldn't mind telling the Wonderbolts that, would ya? 'Cause, I've been trying to get into that group for like, ever!"

"No, Rainbow Dash, we want you to join us, the Shadowbolts!" As the voice said is, three ponies galloped out of the fog and slid to sit on their haunches in front of Rainbow, by the looks of it, the voice was coming from the mare in the middle, I don't like where this is going. "We are the greatest aerial team in the Everfree Forest, and soon we will be the greatest in all Equestria." The mare flew up to talk into Rainbow's ear, "But first, we need a captain." She flew past and began to circle her, "The most magnificent,"

"Yup!"

"Swiftest,"

"Yes!"

"Bravest flier in all the land,"

"Yes," Rainbow giggled, "It's all true!"

"We need," The mare closed in on Rainbow's ear and whispered something to her, whatever it was caused her to jump high into the air.

"Woohoo! Sign me up!"

Now I see what they're doing. I leaned over to Twilight and began to whisper into her ear, "Twilight, they're drawing on Rainbow's ambition to cause her to abandon us!" Twilight turned to me and nodded once, I took it as she understood.

Twilight walked closer to the edge and called out, "Rainbow!" The Shadowbolts mare turned towards her and scowled, her eyes glowing, the fog started to move in, "Don't listen to them!" She frowned at the fog, "I don't think she heard me!"

"Then we must rely on Rainbow and her loyalty, otherwise Fluttershy will have to go over." I turned to the mare, only for her to look away, I frowned.

Meanwhile in Paris, France...
Absolutely nothing related to this story happened.

I looked towards the fog, hearing something approaching, the fog parted to reveal Rainbow Dash along with a repaired bridge. We all cheered and began crossing the bridge, I stayed back and stared as the girls crossed. When Twilight reached the other side, she noticed my hesitance, "Are you coming?"

I looked at her with a sad expression, "I'm afraid I cannot cross this bridge."

Obviously recalling the sea serpent incident, Applejack wade over to Twilight and began a group huddle with the girls. I could not discern what they were saying. When the girls broke away, rainbow and Fluttershy flew back over to me, while Twilight and Rarity readied their horns. "What are you doing?" I asked Rainbow, only for her to wink and ask me to trust Twilight. My eyes widened and I turned to Twilight, shaking my head, "Twilight this is a bad idea! You do not realise what you are trying to do!"

Twilight replied calmly as she nodded to each girl in turn, "I know what I'm doing, I just need you to trust us." Rainbow and Fluttershy grabbed a hold of mr, while Rarity and Twilight enveloped me in a telekinetic aura, "Ready girls?" Twilight asked, to which she got a swift reply from each girl.

"Ready." And with that, they all lifted.

Author's Note

This is hard, I'm trying to keep it so that it doesn't turn into an OC in Equestria fic but it's hard to come up with situations that won't cause the story to go too off track. I still want the mane 6 to defeat nightmare moon, but I want them to have new obstacles because of the fact that FalAIr is with them... So far this is all I could come up with.
