They both went into their rooms thinking of the best possible way to achieve their plan. It would not be an easy think to just sneak in and out of the room unnoticed besides not knowing the exact location of the Etubon in his room assuming he has it would make it even more difficult for them.
Mila could not get some sleep immediately she got to her room as she kept pondering over what had happened and all she discussed with prince Walter.
What she could not understand was the fact that something a prince kept in his room was missing ,who could have pulled that stunt on him and what does the person want to achieve. She did not want to imagine what would be prince Walter's fate if eventually it's not found. She became determined to help him find it no matter what, no just because she pitied him but mainly because of what she feels inside for him.
