I loved Celestia’s ‘Twilight’ style freak out. I love their expressions Now I present an alt incident.

A young Alicorn slips past the royal guard, her manner is non aggressive so she is not restrained.

Twilight: “Princess Celestia, may I speak with you?”

Princess Celestia: “Yes my little pony, how may I help you?”

Twilight: “My name is Twilight Sparkle, The name given me by my adoptive family”

Princess Celestia: “Oh, your birth mother couldn’t care for you”

Twilight: “Oh, I think she could have”

Princess Celestia: “Oh, didn’t she want a child”?”

Twilight: “That’s what I want to know…Mother, oh by the way who was my Father?”

The young Alicorn drops her spell of concealment and spreads her wings. Celestia can only stare at the Alicorn before her.
