The plan

 A woman who was out picking flowers saw Cygnus's form sleeping on the bench. She wondered who could it be since almost no one comes to the rose garden, even his son was not a frequent visitor. With the basket of flowers in her hands, she approached the sleeping man.

She stood at the entrance of the gazebo and wasn't sure how to proceed so she could only stand there and watch the young man as he slept. Not long after she finally left and let him be.

Cygnus opened his eyes after the woman left and sat up to watch as the woman's back disappeared into the manor. He returned to sleeping until Nina found him and called him for dinner. Everyone was present and even the woman who had been staring at Cygnus while he slept. Turned out that she was Linette Ginehart.
