The ending doesn't make sense? Spoilers Farseer & Tawny Man

[Farseer]

As to those that see Fitz and the Fool's parting as false, I suggest that the Fool himself addressed those concerns more than adequately. The Fool may no longer have been able to see himself in the role of the White Prophet - or perform that role - the fact remains that Fitz was still Changer, and it's perfectly plausible to me that to have a Catalyst at the height of his powers paired with and influenced by a Prophet bereft of his own would be tremendously dangerous.

Loving it!
