I can't see anyone aligning themselves with Cersei in the coming battles. Maybe the Freys, but they'll be a rabble without the old guy at the top and will swing to whatever side is winning. Are there any forces left that were sworn to the Baretheons that can still be raised now that Stannis (and Renly to a much lesser extent) are gone? Would they be loyal to Cersei?
So Dany will be aligned with Dorne, Highgarden and part of the Ironborn fleet. She'll want nothing to do with Cersei as she is illegimately holding the iron throne/shagging the guy who betrayed and murdered her dad (who incidentally is her brother)/married the usurper who reblled against her family and took their throne. It will be interesting to see how Euron fares now that Yara is allied with Dany.
Now that YKNJS is the new King in the North, will he march south to clear out the Freys and re-stablish the defences along the Neck? Will he align with Dany, knowing she intends to rule all the kingdoms and probably won't be too keen on allowing the "King in the North" title to continue? Will they align once his true bloodlines become evident (assuming this is because the dragons will choose to not turn him into a Jon-kebab)?
Will the "magic" in the wall which stops the white walkers mean that we get some awesome episode next year where the wall gets smashed and the walkers come flooding through? That would be cool.
Also, did anyone else not give a shit when Tommen jumped? I literally shrugged and went "meh". Zero investment in him as a character.
