Original Description:
 
Luna: “Oh, Twilight! She’s beautiful!”
 
Twilight: “Wait… Luna! Ahgh!”
 
Luna: “WHAT?! Are you okay?”
 
Twilight: “There’s another foal!”
 
Luna: “CELESTIA! GET THE NURSE!”
 
Twilight: “MOTHER OF LUNA!”
 
(About 3 minutes later…)
 
Luna: “Oh, Twilight! He’s beautiful!”
 
Twilight: “OH GOD! THERE’S ANOTHER!!!!”
 
Luna: “WHAT?!”
 
Twilight: “No, I’m kidding. Yes, they’re just the cutest little foals, aren’t they.”
 
Luna: “What should we name them?”
 
(In burst Celestia and the nurse)
 
Celestia: Oh. Guess we missed it.
 
Twilight: YA THINK?
 
Nurse: Well, they’re both healthy. Congratulations, princesses. Which was born first?
 
Twilight: The filly.
 
Celestia: Do you think she’ll be the one to carry on the elements of Harmony?
 
Twilight: I hope so. Not that this little one- (she gestured to the colt) -isn’t up for the job.
 
Luna: We should name her Harmony!
 
Celestia: Yes. Harmony. Beautiful.
 
Nurse: What should we name the other little one?
 
Twilight: Apollo, maybe?
 
Celestia: Apollo was the name of the unicorn that murdered my parents, Twilight.
 
Twilight: Oh. Sorry.
 
Luna: It’s alright. It’s been almost 1500 years.
 
Twilight: Well, maybe Artemis?
 
Nurse: Yes. Perfect. Harmony and Artemis. Welcome to Equestria.
