They really made sure Rickon was not coming back, pounding him with arrows and Jon immediately ordering him buried in a crypt. To me it is an indication of no Lady Stoneheart and no more resurrections.

I believe Varys is going to meet with the forgotten bastards, the Sands, to get their support. Nobody seems to be talking about this, but it would make sense since they started the season with their coup and Myrcella murder. They will probably fight the Lannister bastard Tommen!

It seems to be that way. GOT has a way of breaking your heart, I predict Jon loses the battle because of Sansa expecting help from Littlefinger and being betrayed once again for being so naive!
