No, it wasn't that she forgot. She simply hadn't expected it—hadn't expected that the wet nurse, whom she had treated as a daughter, would betray her and even confess her secret with her brother.
"How could you… how could you betray me…"
How could she betray her? She had killed everyone else but spared only the wet nurse, and yet she was betrayed like this?
"My lady, this old servant truly could not endure any longer. They were too cruel! This old servant was in pain!"
The wet nurse also knew that betraying the Empress was wrong. She knelt on the ground, wailing and begging for her forgiveness.
If she had any other choice, would she willingly betray her mistress? But what options did she have? Her family, over a dozen people, were in their hands. They even tortured her.
If she didn't reveal something, how could she hope to survive?
"My lady, please save this old servant, save me!"
