Of course, as others have expressed, I am also somewhat skeptical of Ta Wan being the sire. Not only was he extremely young, but Ta Wan is much smaller than Farina overall, and he is specifically very short of leg as well. I honestly don't know how he would have managed to reach her to breed short of Farina squatting down on her knees, which would likely set her too low for successful penetration anyway. But the optics of an accidental half sibling breeding are far worse than that of an accidental breeding between Po Chin (who is unrelated) and Farina, so I see no reason why the park would lie about it.
