Maybe, I think we might see another battle at castle black in the aftermath of Jon's murder. One side would be members of the watch loyal to the mutineers, the other would be members of the watch loyal to Jon, the Baratheon faction, and the wildlings under Tormund. I think she might think Stannis is dead when she burns Shireen, she hasn't been able to see him in her visions and the pink letter says he has fallen fighting at Winterfell. She'll think all is lost because Azor Ahai has fallen and try and work great magic to save the world.

I think it will take awhile before we get Jon POV. My theory is that Mel will parallel Dany's burning of Drogo's pyre and waking the dragons when she resurrects Jon. I expect her to burn Shireen where Dany burnt Mirri Maz Dur. I expect Jon to be on the pyre as Drogo was. I expect Melisandre to even walk into the fire as Dany did. Hell I expect the red comet to return and be seen burning in the sky. Picture Jon's body placed atop a great funeral pyre and Shireen tied to a stake screaming for her mother to intervene as Selyse watches on consumed by religious fanaticism. As the fire takes and the pyre ignites, the red comet is seen returning. Melisandre walks into the fire and kisses Jon, she dies, Jon awakes, the chapter ends. In Bran's next chapter he coaxes Jon's soul from Ghost back into the resurrected Jon. Then the next morning Jon, his hair burnt off walks naked from the ashes of the fire, starting his first POV chapter of the book. From there this newly resurrect Jon will probably be more brutal having some of the wolf in him all the while being looked on with awe by those around him.

I don't think they arrive until after the battle, it'll give the surviving POVs something to do until Dany gets back.
