You must have checked his stats at gauntlet, in 1199. In 1200 Favours changed to Tormenting Master after a faux-pass in the Normandy Tribunal. His current stats should correctly reflect that.
I've put a short description of Valerian (and his opinions on Regulus) here. There is more about him in the Normandy Tribunal book, p.137 (I can write an abridged version of that if it makes things easier on you ^^).
