Speaking of Inconsistencies - When did Shrewd meet the Fool

[webof63]

In the first book, Fitz speaking as a Narrator comments on seeing the Fool and how he had recently arrived to Buckkeep, but in the Fool's Errand (I believe) the Fool mentions that he had been looking for Fitz (his Catalyst) when he came to Buckkeep. In fact, the Fool says during that conversation that he had overheard Shrewd and Chade talking about Fitz and thus first learned of Fitz's existence.

So my question is . . . are these two statements inconsistent and if so when do you think the Fool met Shrewd?

Actually the fool said he came to Buckkeep to look for a Farseer, instead he found Fitz instead, a bastard but nevertheless a Farseer.
So the Fool had been at Buckkeep before Fitz arrived, and through the conversation Shrewd and Chade he learned his Catalyst had arrived.
