Caroline was already sleeping soundly in the guest room of Allison's house.
Meanwhile...
At Susan's house.
Mike was having a hard time sleeping that night. It's the first night of his wife's disappearance, he can't sleep, his mind is busy thinking where his wife is sleeping right now?
Whose house she was staying currently?
Was she sleeping with another guy? He winced with the idea. He can't help but think of that possibility sometimes...even though he doesn't want to entertain that kind of thought much because it will only make him mad with jealousy.
But right now that Caroline wasn't giving him any specific reason for her disappearance then all scenarios are possible.
How many days, weeks, or months he had to endure all this? When is Caroline able to sort out her problems and come back to him?
When she returns... will they stay the same or there are changes?
