Cady and Nighthorse??...possib le??

So I think this is already picked up by others, but towards the end of season 5, there seemed to be some serious tension between Cady and Jacob. Before, I just chalked it up to common cause, willingness to work together, and Cady spreading her own wings, so to speak! But in episode 8-9, there seems to be something of a tipping of the scales? A subtle change in their interactions, especially when Cady aligned herself with Jacob, and hoped that he didn't think the shared her dad's opinion of him. To which his response was that she obviously cared enough for him to warn him.

Are audiences reading too much into this? Clearly the writers don't have an issue with age difference, if Vic and Walt are dancing around each other. How would people feel if Cady and Nighthorse became a couple? It would certainly throw a massive bone in Walt's already crazy life.
