Nurse King: Fake History

I do understand the necessity of the story, meaning as to what Nurse King had done to Abe, I get that, but this has nothing do with that, what I’m getting at is that there are way too many people who can certainly bring up the airdate as to when Coles as Nurse King was first seen, would negate the story as to what had happened to her husband & her cats, especially given the date that the viewers had seen the character, would not have created the illusion that she was in Salem when Marlena was possessed, when Marlena morphed Jan into Belle, when Johnny was possessed, now was she?
