If you recall, Paige had said that Carl refused to let Harvey stay in his house and that’s why he had a rental down the block. Me thinks it’s for this very reason. Harvey would end carls life if he saw him hurting Katie.
Regarding the bruise: katie spent hours in hospital. There’s no way they wouldn’t have noticed it was makeup.
I can see that being the truth, I bet Carl didn't want Harvey in his house because of the damage he has done to other houses he has lived in, which has been well documented by KP herself ( somewhat proudly, strangely!). From pictures we have seen of his house it looks as though he is quite houseproud, everything neat and tidy, unlike her houses. In that respect though it must be really hard for him to live with her, given what a pig she is and what a
tit hole her house always is! Remember when Kris moved out and she had some cleaners in and tried to blame the mess on him?
