My endgame for some of the characters:
I predict that Dany will fall in love with Jon soon (maybe starting next episode). They will be betrothed at some point, but then near the very end of the series, Jon will kill her to save Westeros or to slay the dragons in a pact with the walkers or something.
Arya to be the last Stark in Winterfell, living the life that Ned said she would and she never thought she would.
