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.
