Lynette confronts Ed for driving Tom to do it and he shows her one of Tom's expense reports that includes a side trip to Atlantic City and tickets for two to a show and flowers. When Tom comes to clear out his desk, he tells Lynette it's for the best. And she asks if there's anything else he wants to tell her and he says "No."
