He should compare notes with Deanna Troi sometime  ;)

You mean, so that he also begins to announce useless gibberish about people he meets anytime someone asks him? :)

I was thinking more about using his special ability for cunning, smart moves to gain advantage over opponents and enemies. But then, thinking about it, that might stretch imagination too far, really. (sigh) ;)

In The Great Hunt, when they are chasing Fain and the Horn of Valere from Sheinar, and after Rand, Hurin, and Loial accidentally use the portal stone. They don't have Hurin to track the Trollocs so Perrin has to be a stand-in sniffer. So, everyone in that party-- Mat, Verin, and a few random Shienarians-- knows that his sense of smell is somehow enhanced, if not the full extent of his abilities.

Other than that... idk, can't think of a time when it's mentioned explicitly.

Yes, that's true, thanks for pointing me to that scene, I remember it now. And I also think there is no other event like that.

The reason I find this question interesting is this: the ability to know, through smell or otherwise, the precise state of emotions of someone you talk to is one of the most powerful and useful things I can imagine! Particularly if you are constantly dealing with people who are either more powerful than you are, or want to harm or kill or manipulate you, or all of that, like Perrin certainly has to quite often.

He doesn't make much use of it, and in The Gathering Storm he even wonders why others don't recognice smells as he does. He even thinks that they simply don't take the time to concentrate on matters.

Just imagine how useful this kind of knowledge would be to some of the people around him. Like Faile, who is rather skilled at manipulating people in her own right...

I have a question about Perrin: who (except Elyas) knows about his sense of smell? I know that Faile (and most others around him, after KoD) know some or all about his sharp eyes and ears, so I always assumed that he also told at least Faile about his sharp nose, too. I cannot recall any reference to that, though, and the few scenes after Malden wouldn't make much sense if she actually did know.

So. Has he told anyone? And if not, why not?
