Naura nods her head slowly, indicating that she digests well what Diandra is saying. It's just thathe still doesn't have the courage to express it.
"Forget it then," said Diandra then walked away from Naura who was still standing glued to the pool.
Naura is increasingly overcome with guilt with her current decision, making Diandra feel disappointment. Infact, it is possible that if he conveys what he knows, it could make a reason for Diandra to call his memory.
"His brother...."
Diandra stops her move, giving Naura a chance to reveal what she really knows. Actually,Diandra is so curious to know what Naura wants to say. It's justthat, he has to use tricks to get the girl willing to reveal it without having to be forced.
