Yes. He did look like Aniuta. But it was the Aniuta of later days to whom he bore a resemblance. The tired sullen droop to the eyelids, the skeptical - in him scornful - curl to the full lips. There was not a sign of the golden-haired girl with her hunger for danger, for righteous glory, her bursts of wild invective. Of that creature Urey would have no memory, only of a sick woman, shapeless, asthmatic, cancerous, declaring herself eager of death.

I wonder what would have expresses in this context. Is it conditional (no), habit (no), future in the past (?) or does it express opinion (?) or conjecture ? In my opinion, it's supposed to express possibility or rather the opposite in this context. But can would express possibility? It's a mystery to me actually. Please help. Thanks in advance.
