I took his passages about the city as foreshadowing to his "relationship" with Nastenka.
"She reminds me somehow rather forcibly of that girl, ailing and faded, upon whom you sometimes look with pity or with a certain compassionate affection, or whom you simply do not notice at all, but who in the twinkling of an eye and only for one fleeting moment becomes by some magic freak of chance indescribably fair and beautiful...And you feel sorry that the beauty, so momentarily evoked, should have faded so quickly and so irrevocably, that she should have burst upon your sight so deceptively and to so little purpose-that she should not have given you time even to fall in love with her..."
Sound familar?
