I think it is N because N seems more in your face than A .
I also used to like cowboy , but I can't wait til he's outta there now. I hope he's the replacement for Jace.
I also don't trust Karen at all . I was kind of shocked at her blubbering when Holly got the heave -ho . She had shown no overt tones of that kind of closeness in house. That leads me to wonder what or who else she is hiding.
