Dumbledore watched her fly away, and as her silvery glow faded he turned back to Snape, and his eyes were full of tears."After all this time?""Always,"said Snape.

Dumbledore had watched a woman fly away, and once she was out of sight, he looked back at Snape and tears filled his eyes. Dumbledore asked Snape in a sad tone, “Even after such a long time?” Snape simply replied, “Always.” This meant that even after so much time had passed, Dumbledore was still holding true to the woman he had watched fly away. Snape was saying that no matter how much time had passed, his love for the woman was eternal and would never change.
