Princess Celestia: [to Twilight] This is your victory as much as theirs. You persisted in the face of doubt, and your actions led to your being able to bring the real Princess Cadance back to us. Learning to trust your instincts is a valuable lesson to learn.

Princess Cadence: They'll never get the chance! Shining Armor's protection spell will keep them from ever even reaching us.
Queen Chrysalis: [chuckling] Oh, I doubt that. Isn't that right, dear?
Shining Armor: [she makes the brainwashed Shining Armor nod his head absently] Mm-hmm.
Queen Chrysalis: [Angry, Princess Cadence starts to run towards Shining Armor, but Chrysalis stops her by stomping her hoof down] Ah, ah, ah. Don't want to go back to the caves, now do you? [she glows her horn green as a threat] Ever since I took your place, I've been feeding off Shining Armor's love for you. Every moment he grows weaker and so does his spell. Even now my minions are chipping away at it. [cut to above Canterlot, where the Changeling army is definitely hammering away at a weakened shield]
Queen Chrysalis: [laughing] He may not be my husband, but he is under my total control now. [Twilight and Cadence gasp]
Queen Chrysalis: And I'm sorry to say, unable to perform his duties as captain of the royal guard.
Princess Cadence: Not my Shining Armor!
Queen Chrysalis: Soon, my changeling army will break through. First, we take Canterlot. And then, all of Equestria!
Princess Celestia: No. You won't. You may have made it impossible for Shining Armor to perform his spell, but now that you have so foolishly revealed your true self, [they lock horns] I can protect my subjects from you! [Celestia flies up and unleashes a powerful beam from her horn at Chrysalis]

Twilight Sparkle: [after Chrysalis and the changelings have been defeated, the wedding continues as normal] Seriously, though. I get why the queen of the Changelings wanted to be with you, but how did you get someone as amazing as Cadance to marry you?
Shining Armor: I told her she wouldn't just be gaining a husband, she'd be getting a pretty great sister, too.
Princess Celestia: [to the gathered crowd] Mares and gentlecolts, we are gathered here today to celebrate the union of the real Princess Mi Amore Cadenza...
Princess Cadence: [humbly] Princess Cadance is fine.
Princess Celestia: [smiling warmly] Hm. The union of Princess Cadance and Shining Armor. The strength of their commitment is clear. The power of their love, undeniable. May we have the rings please? [Spike presents the rings on the pillow, and Celestia levitates each ring onto the couple's horns] I now pronounce you mare and colt. [cheering from everyone in the room]
