[This pony looks disappointed. Mabel does not want to have disappointed the cute pony. She smiles, cheerful and friendly, everything is okay cute pony!]

Hi Fluttershy. Someone you knew, huh? Do I have a secret triplet out there or something, haha?

[What a silly thought, who would ever come up with a twist like that?]

Anyway, it's nice to meet you. Do you shake hands?
