So I decided to hire Belrand in Solitude. According to the strategy guide and internet wiki pages he should be proficient in Destruction and Restoration spells as well as one handed weapons. However on our travels we came across a dragon and he whipped out a bow, something that didnt appear in his inventory when I checked earlier, before we set off. Also the only spell I've noticed him casting is Summon Familiar, which to my knowledge is actually a conjuration spell. Is this right and also is it possible to teach spells to followers?
