In the Dark Knight Rises during the ending scene, we see that Alferd is crying in front of Gordon and Blake at Bruce Wayne's Funeral. After sometime we see that Alferd sees Brue Wayne and Selina Kayle at a place (as he had imagined once). So I want to know that when did Alfred come to know about the reality of Bruce's death?
Had he known it all before because if that is the case then his crying at funeral was just a mask to fool Gordon and Blake.
Or is it that at that time he genuinely believed that Bruce is dead and only later he came to know that he is alive and where to find him?
