I was wondering the same thing. Especially in light of Ramsay's talk with Roose about marching on The Wall. Last we heard from Littlefinger, Cersei gave him approval to take the North with the army of the Eyrie. Ramsay and Roose were talking about how depleted their forces are. I thought the show was leading up to us checking back in on what Littlefinger is up to; then nothing.
I am guessing it will tie together at some point though. If Ramsay is intent on taking the Wall, it will only make the North even more susceptible to Littlefinger's attack, especially with Roose's claim that attacking the Wall will turn virtually every house of the North on the Boltons. It could make the North all the more vulnerable to Littlefinger rolling in, deposing the Boltons and declaring his intention to marry Sansa and Robin Arryn. Virtually the entire North but the Karstacks would rally behind him.
I suppose what I am saying is that while is not in the episode, if his intention is still to take the North, the deck is even more in his favor.
