A Free Spirit
Dubbo is definitely I think a free spirit, just look at the extracts we've examined in class. His looking out the window when he wakes up, painting a picture in his mind's eye as a means of commenting on the world, thinking about the way the imperfections in the glass shape what he sees outside.
And later, when Himmelfarb is being crucified, the way Dubbo seems to be removed from the reality of the situation and is somehow "overlooking" things from some higher plane of existence - he cannot help Himmelfarb (or at least chooses not to) and yet he immediately connects religion and salvation (with the comments on the Mary's) to what is going on - he does not physically engage in life, but he is a spiritual node of existence.
I wonder how the situation would have come across through someone else's eyes? Say, from another perspective.
Dubbo's dream like state is somewhat his whole existence...just as Blake saw the world ahead of his time, perhaps Dubbo is seeing what others cannot - and he is attempting to convey this other worldly knowledge to the world through his art.
