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

[fool-ish]

A coupling between Fitz and Kettricken cannot be incest if there's is no blood connection. Any civilised people would surely see that and have no problem with them having an intimate relationship. Nor do I believe Verity would even think of using Fitz to allow Kettricken to conceive, if he thought for one minute it was incestuous. I think a relationship between Kettricken and Fitz only didn't happen because of all the political shenanigans, Fitz' life as a whole and Molly. I do feel they came very close to it at times, however and a part of me does like to think that Kettricken was aware it was Fitz.
