I read the first trilogy in Finnish decades ago, which doesn't have gendered pronouns. As such, the topic of Fool's gender got somewhat buried.
By the time the topic comes up in the third trilogy by Starling, Fool has already presented themselves as both Lord Golden and Amber. I would also recall that Fool said to Fitz that both were real aspects, and neither was a disguise (any more than other presentations they did).
