Yeza was a precocious child. That much had been obvious right away and even had quite reasonable justifications.
Having mana from birth was a significant advantage that bolstered every physical function, even before gaining any control over that energy.
Yeza was also part Niqols, a species that reached physical maturity far earlier than humans. A quicker development was the norm for her.
Lastly, Yeza had ancient horrors' genes, granting her hunger disproportionate to her size and age in exchange for strange abilities and superior toughness. She never had any chance of being normal.
Still, despite all those inborn advantages, it was quite evident that Yeza's previous words didn't really refer to Khan. She was simply too young to make that mental connection and realize what it meant.
Chances were, Yeza had only misspoken or had adjusted her usual "ba-ba" after Khan jokingly corrected her multiple times.
Of course, none of that mattered to Khan.
