Mrs. Johnson doesn't see as much as she thinks she sees, if she's coming around to the idea of David going away from Laura. She means well (in this particular case) but she doesn't get it.
It's sort of strange to see her still reporting to Burke, since the Burke's revenge plot isn't emphasized much at the moment. But Burke doesn't know that his creators have shoved him to the back burner.
Despite Burke's belief that he and Laura are headed for a rosy future together, he still feels protective towards Vicky, and Laura knows it know. That could make for some interesting interactions, if only Laura cared about Burke as much as she tells him she does.
