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

[Nuytsia]

But as to his general ability to open and close the door to a room silently and without being seen I have no idea!!!!! I guess just very stealthy. As to his not being detectable to the Wit and having no smell.... that started to really creep me out reading AA and the bit where Fitz realises the Forged ones are undetectable to his Wit sense.
I have already forgotten whether it is explicitly stated in AA that the Fool is undetectable to Fitz's Wit sense, but it DOES say that the puppy Smithy realised the Fool had no smell and that's when Fitz first realised that too. What DOES it mean!!! (apart from my initial suspicion that the 6 duchies people just don't wash very often in comparison....)

Replying to myself here, but I've always wondered about Fitz (and Smithy) saying that the Fool had no detectable smell. So I'm re-reading the LST books and of course immediately went WHA? when I read that when Amber had a nightmare Paragon could SMELL her fear sweat. So it would seem that Amber is not without smell? (unless this is just an oversight by RH...... I guess it COULD happen!)

But then I came across Farseer's comments in another thread (below) that mention that a glamour can involve influencing smell. And although Lord Golden says Fitz is the only one not taken in by his glamour I have serious doubts on that. Then again, it would mean the glamour would have to have been working before he was Lord Golden if it indeed IS what makes him seem to have no smell.
Seems a lot of trouble to go to though!!
I would have thought it more likely a 'natural' thing rather than a glamour.
If so, not sure why Amber smells

The Others were able to change their appearance, smell etc through the use of a glamour over visitors to Others Island (Fitz saw through it, Dutiful was mesmerised by it and Kennit was a bit of both on different occasions, though his charm eventually allowed him to recognise it for what it was).
Fool even spoke of himself as having a glamour and it was this that enabled him to successfully maintain his role as Lord Golden (I thought this was particularly interesting!). At one point, Fitz asked him how it was that he had suddenly become so popular at court. To this, Fool complained that everyone was taken in by his 'glamour' except Fitz...it was only Fitz who could see through it and so saw him as he was.
