Robin and his secret agent

"How long will that memory stay in Zwetta's memory, doc?" asked Robin seriously as doctor Giana sat across from him.

"As long as Zwetta is not reminded of all the events that have occurred over the past four years, those memories will remain in her memory," answered Doctor Giana expressionlessly. "That's why we have to make sure Zwetta doesn't remember all the things she's been through with the husband and wife or the people she knew in Luxembourg."

Robin immediately straightened up. "So you think we should prevent Zwetta from re-interacting with people she's known during her memory loss for the past four years, doc?"

"That's right, the only best way to make Zwetta not remember all the memories that you want to erase from her is to prevent her from interacting with these people again," said doctor Giana indisputably. "You can confirm that, can't you?"

"Of course, it's an easy job for me," Robin replied coldly.
