The Birth of Sunlight/Brian apologizes

Here's how the birth of Princess Sharon goes in Revenge of the Nightmare Family & Changling Queen.

["Revenge of the Sith: Birth of the Twins" starts playing]

Princess Luna: You're doing fine, Tia.

Barret Barricade: Cadance, you see anything?

Cadance: No. Wait, I see the head! Push!

Princess Celestia: [groans]

Barret Barricade: [rubs her hoof] It's alright, keep pushing!

[Then with one mighty push. She pants]

Cadance: Oh, my Crystal Empire!

Shining Armor: What? What's wrong?!

Cadance: It's a female, alicorn filly. [holds her up]

Filly: [crying]

Princess Celestia: She's beautiful.

[Cadance hands her over to her]

Barret Barricade: She has your coat.

Princess Celestia: I know.

Shining Armor: [opens the door] Alright guys, you can come in now.
