Not to worry about going off topic, these tangents are often much more interesting!
Molloy's depth and transience as a character is profound indeed, and that fine 'line' as you put it between personalities and people quite troubling. I find him a lot more readable than Joyce's stream of consciousness in 'Portrait of an Artist', mostly for the insights on consciousness which he brings to bear. Beckett's work generally is pretty mysterious - there's few others like him.
Appreciate your perspective on this :)
