Kat's husband was having an affair with their neighbor, Janine. 

Will, Cleo's new boyfriend, was also her professor. He was the man that Kat had "killed" all those years ago. He was the one blackmailing her and he was the one who injured Cleo. 

But she wasn't dead. George, the neighbor with dementia, had her at his house keeping her safe. He just lost track of the days.
