Nadia's expression flickered.
Korra, unlike the rest of the world, knew the truth.
It wasn't that Astrid's father had disappeared or died.
The truth was that Astrid had never had a father in the first place. She had only had a mother from the very beginning.
But despite knowing that, Korra never knew exactly how Astrid had been created.
"So how is it possible, Nadia?" She asked curiously. "How exactly did you give birth to Astrid without an actual partner?"
She scratched her head, thinking.
"One time, a couple of years ago, when both of us were drinking, you got particularly tipsy. And you told me it had something to do with Mika's mother."
Nadia's face went completely still.
Korra didn't notice. She was too lost in her own recollections.
"Based on what you said, I wondered if both of you and Mika's mother got hot and steamy in bed and did the impossible, and you became pregnant with her child."
She laughed, clearly treating it as a joke.
