Take a look at a few times in Truth Be Told and Impossible Dream that Renita Hayweather was referenced.
Note that in each of these instances, Renita Hayweather was being used towards a particular end, or to reveal some sage piece of advice or insight that proved enlightening.
Take for instance Norman's request to finish reading Frontier Duchess. As discussed in Norman's House Rules check-in, the book became a bible of all things Rita, allowing him insight into her heart previously unavailable. He used it to begin leading their relationship, a road map to ease his anxiety about "what to do [next]," the concern Norman revealed to Oliver in Truth Be Told.
For Rita, the Frontier Duchess, as discussed in both House Rules and House Rules 2, has been an integral part of her growth. Rita has proven she is more than capable of writing her own future, no longer needing Renita Hayweather as a crutch, and instead using it as a tool to advance that future.
An early instance of this is when Norman asked her if Frontier Duchess had a happy ending. While she reassured Norman that it did, Rita also alluded to her intention to rewrite it to make sure she got things right. In doing this, Rita allayed some of Norman's concerns, which seemed to fall along the same lines. She used the Duchess to negotiate a space in her relationship with Norman that they hadn't quite found the courage or vocabulary to express to each other otherwise.
Much like Shane and Oliver found ways to discuss and navigate their complicated relationship through Norman and Rita, Rita and Norman have followed suit, using Renita Hayweather as their negotiator until such time as they feel more comfortable addressing their relationship head on.
