"NO!" cried Rainbow Dash, watching her love interest fall towards the Earth. Desperate to save him, she told Gilda,"Take care of Lightning, I got to save Soarin!"
"Are you CRAZY?! Your wings are injured! You'll just fall with him!" Gilda tried to knock some sense into Rainbow.
"Just go, I'll catch up somehow!" Rainbow replied, before removing herself from Gilda's grip, falling in eagle-dive position to reach the falling Wonderbolt.
As amazing as it was, when Rainbow reached Soarin, she eventually kissed him on the lips, freeing him from the spell Lightning placed on him. Regaining his senses, he stopped his and Rainbow's fall, carrying her in his front hooves.
"Rainbow Dash!" he called his bride's name, before asking, "What's going on? Why are you all messed up with clipped wings? And, why are we in the middle of the sky?"
"It's a long story," Rainbow replied.
But before Rainbow could say another word, Lightning Dust's voice interfered, "Leave me alone, you BEAST!" the wicked pegasus called out to Gilda, who was chasing Lightning.
"Why don't you leave me and every creature alone instead, lame pony!" Gilda called back.
Insulted by being called 'lame', an outraged Lightning Dust shouted, "HOW DARE YOU CALL ME LAME!"as she charged at Gilda with full speed, only to fall for a trap the griffon and Scootaloo had set up. Lightning ended up trapped in a net, that was hidden behind the opaque clouds before she touched it.
"It's over, Lightning!" Rainbow exclaimed, as Soarin flew her to the trapped pegasus.
"Over?!" Lightning asked, before laughing and replying wickedly,"It only just BEGUN!"
Finishing her sentence, Lightning moved the net towards Gilda's sharp griffon claws, using them to cut open the net. Once freed, Lightning Dust charged towards Rainbow Dash, in a final attempt to ruin the heroine's wedding, the villainess was going to finish her.
Just as Lightning was about to reach Rainbow, Soarin hugged his bride tightly, trying to protect her. The pegasus couple's love for one another eventually activated a special kind of magic in the process, preventing Lightning Dust's attack, sending her falling backwards. To Lightning's horror, the power of Rainbow Dash and Soarin's love was just like Cadence and Shining Armor's, as it levitated the couple in the air, as their eyes glow white, before sending a shocking wave that sent Lightning far away, out of Equestria.
After Lightning Dust's defeat, Princess Twilight appeared, having returned from saving the falling creatures earlier.
"Every creature is saved and safe," she told the Pegasi and Gilda, before apologising to Scootaloo and the said griffon,
"Scootaloo, Gilda, I'm so sorry I didn't listen to you two! I should have been more aware, having experienced the same thing, during the royal wedding at Canterlot long ago. I can't believe I didn't sense something odd with my own best friend's imposter!"
"It's okay now, Twilight." Scootaloo assured.
"Yeah, we all made mistakes, and have acted like jerks from time to time," Gilda added.
"But what's most important is, everything ended fine in the end." Scootalo pointed out.
"And you brought the real Rainbow Dash back to all of us," Twilight gladly responded.
"Rainbow Dash!" called Bow Hothoof, Rainbow Dash's father, as he flew up to his daughter.
Windy Whistles, Rainbow's mother, followed him as they asked their only child, "Are you okay?! Did that mean pony hurt you?!"
"Don't worry, Mum and Dad," Rainbow assured, "I'm okay, thanks to my adoptive little sister Scootaloo, and my first non-pony friend Gilda. I would never be here if it weren't for them to find me."
"And we would never have found you if it weren't for our suspicions," Gilda added.
"And Lightning Dust's behaviour when she was pretending to be you." Scootloo ended.
"We're all glad to have the real you back, Rainbow Dash," Soarin told his bride, before turning to her friends.
"Scootaloo, Gilda, I'm so sorry for what happened at the rehearsal," he apologised. "I can't believe how oblivious I was to Rainbow's imposter's attitude, especially when she was demanding. Can you two forgive me?"
Scootaloo and Gilda looked at each other, before accepting his apology.
"We totally forgive you," Scootaloo replied.
"Yeah, as long as it never happens again," Gilda added.
With everything resolved, Princess Twilight told every creature, "Now we have a real wedding to put together."
