Thus far, I believe that Magnus' irritation has been at least somewhat justified.  He took being incorrect in great stride, not one to stubbornly insist that he's right when shown the contrary, but took issue with the concern that he was going to be a liability.  For a warrior whose main goal in life is to pursue the protection of others, that was something he felt he needed to address.  But he's still merely a man, and sometimes men let themselves get carried away.<br/><br/>Does he especially<em>like</em>Valenar based on their interactions thus far?  No.  But at the same time he believes that Valenar is a good man, and that you don't need to like everything about a person to consider them worthy of working alongside.  Nor does it mean that he is unwilling to put any differences aside in order to do so, so long as it does not involve going against the Code of his order.  Magnus is not a man to hold grudges, so once on the march I don't see him continuing to antagonize the elf.<br/><br/>Does that make sense?
