He can’t abandon his son after all.
This right here, when Nate says he should be in Kansas, "with your son," that hit me personally harder than any other line in the show so far.
Rupert may revel, but Keeley is one smart cookie and she's wise to Rupert's ways. What we didn't see was the conversation between Keeley and Rebecca about this possibility. Somehow I think the two of them are already on top of that. Maybe season 3 will be about how goodness, honesty, scruples and integrity triumph in many of the story arcs, and how all of Rupert's money can't buy what he wants.
I don't want to be the wet blanket, but I think the whole "goodness, honest and integrity" angle will be a lot more subtle than that. Ted will learn how to meld Beginning Ted with Healing Betrayed Ted to become At Peace Ted, which includes accepting other instincts and keeping them in their proper place (which isn't always "push down into a little hidden location forever").
Thesis, antithesis, synthesis. (I referenced Kant! The world is ending! Only Ted can save us, because if he Kant, then who can?!)
