Here is how the Honor of Yuna begins and the movie ended in Yuna and the Return of the Princess.
At Canterlot, Yuna and her friends are settled to their homes.
Princess Yuna: (voice over) And finally, We were home after all we've been through.
Princess Luna: Peek-a-Boo! Boo!
Prince Isamu: (giggles)
Oh: Isn't it great be back in the home?
Prince Edmond: It sure is, Oh.
Princess Celestia: Dear Friends, We are gathered here to honor my niece, Princess Yuna and her friends for saving Equestria and all other worlds from the endless wrath of the Demon Lord, Chernabog.
Everyone and Everypony cheered.
Princess Celestia: We're so proud of you, Yuna.
Princess Yuna: Thanks, Aunt Celestia.
Outside, They bid farewell to Star Swirl.
Princess Yuna: Well, That was exciting. Other then that, It was heroic.
Princess Luna: You've made everything possible, Yuna.
Princess Yuna: I sure did.
Princess Luna: You had our thanks, Star Swirl.
Star Swirl the Bearded: And now I must return to my home.
Princess Yuna: Until we meet again next time.
Star Swirl the Bearded: Farewell, Princess Yuna.
Yuna smiled and Star Swirl magically disappear and Yuna and her mother returned home.
