Looking at Clark, who was still struggling and screaming on the bed, Dave felt deeply unsettled. He instructed the nurse,
"If anything happens, call me. I'm leaving now."
Then he quickly walked out.
In the past, every time he visited, he would sit for a while, comforting Clark or keeping her company, hoping to help her recover sooner.
The sooner Clark recovered, the sooner he felt he would be free.
When Clark first returned, her emotional state had been very poor, and she had become terribly thin. She cried all night, talking about suicide and similar things, so he had to stay with her.
But this time, he didn't know why, but he just wanted to leave as quickly as possible.
