The Fool (spoilers for all RotE books, including LST)

[n00854180t]

The Fool dressing him up, to me, was like a spouse or partner picking out the clothes that they always wanted to see their lover wearing because they knew how much more attractive they'd be, maximizing potential.

Having been subjected to this by my ex-wife in reality, this if how I saw it as well.

Also, the Pale Women was Female, because Fitz saw her nude body. And the Black Man was male. And the Fool said he was male when he was desribing to Fitz that he loved him, but that did not mean he wanted to bed with him.

The issue of the Fool's gender is also rather satisfactorily cleared up when Fitz retrieve's the Fool's body, before resurrecting him. In fact, that was the point at which the question of the Fool's gender was actually cleared up in my mind. I believe it would have been mentioned if the Fool had been female, and it was not, despite the fact that the Fool was definitely naked during this period.
