For a character who so reveres wisdom and knowledge, I feel that he would have an intense curiosity about the world and people around him. I think it's time for Raziel to branch out a bit more and show more of an interest in the other characters. While it wouldn't be in-character of him to put anyone through a personal interview process, I guess that what I'm saying is that I'm interested in seeing more of his curious, observant nature in action, especially in helping Asgard discovering Niflheim's weaknesses.
It's all great to have an anti-social, snarky angel in the game, but I wish to see him get out of his comfort zone more often.
