When Altaïr was last in Asgard, he was calm, level-headed, understood and followed the Creed. He was steadfast but respectable, and knew how to respect those he did not know within the Brotherhood.

[Can you tell where this is going yet, Desmond? Ezio gives an unamused look as he continues.]

From what I have heard and now seen of him, however, he is nothing more than stubborn and full of pride. He holds no respect save for his Master, and everything he does he views with arrogance.

[It's clear Ezio doesn't take this well, especially since he holds much respect for Altaïr in general. But the flighty and testy attitude he was given a few days ago, not to mention what he has heard of the other's actions, is leaving the Mentor disappointed.]
