Anybody ever wonder just exactly what the relationship was between Alister and Jebediah? Clearly, from Camber's assimilated memories and the scene where Camber has no choice but to engage Jebediah in rapport and forces upon him the hidden truth of Camber-Alister, they were quite close. There was a phrase, I can't remember where, mentioning Jebediah leaning against Alister's knee whilst they sat at a campfire, which seems to me to be a position of great familiarity.
On the one hand, in the world of medieval Europe, people touched each other more frequently than most modern peoples of the native English-speaking world. It was not at all uncommon for people to kiss each other's cheeks and exchange a hug upon meeting, and even in the circumstance of a subject meeting a ruling monarch, the monarch would offer a hand for a kiss either on the hand or at least on a ring. (What ordinary citizen would dare kiss President Obama or PM Brown, for example? Note the recent furor over Michelle Obama and Queen Elizabeth exchanging a one-armed hug.)
Also, at that time, physical contact with a friend of the same sex was more acceptable than now, as physical contact with members of the opposite sex was rather frowned upon unless the people were closely related by blood or marriage.
Furthermore, Alister and Jebediah appear to have been in a number of combat situations together, and that is, as I understand it (having never been in combat myself), quite the bonding experience, often rendering such people closer than siblings.
Camber never appears to suspect anything other than close friendship and deep personal loyalty between Alister and Jebediah, but it just makes me wonder if they were more intimately involved.
