Sleeping
She was putting on a light gown and with the cold wind and AC on in the parlor; she sure must have caught a cold.
He traced her gaze and realized that she was staring at the bed; and that moment, it occurred to him;
THERE WAS JUST ONE BED IN THE ROOM!!!
Wait, how did he not think about it all the while! Throughout the trip, even till that evening, it was now he was just realizing that they would share a bed!
What was he thinking? He had never slept in the same room with anyone before; talk more of the same bed! Why didn't he remember all these when grandma asked them to come over? He was just thinking of how he would get closer to her and he forgot the most important details.
What would he do now?
Nicklaus ransacked his brain and for a moment, his eyes shifted to her;
She must have thought of all that, that was why she had been uncomfortable all the while; she must see him as a big jerk!
