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

[Farseer]

This thought bears significance not only with regard to Fitz's role in the Farseer and Tawny Man books, but also any role he may or may not have in future books. It is so simple when applied to the definition in this way and, as the readers, we were maddeningly given all of the info we needed to make this connection very early on (the naming ceremony and all of Fool's conversations regarding 'the catalyst'), which makes it even more mind-blowing. Just goes to prove that Robin knows very well where she's headed with it all...

I can't help but notice the 'cat' in catalyst now either!
