I think Daenerys and Jon Snow will join up to beat the zombies and then to take out the Lannisters but then Jon Snow will go back to Winterfell and Daenerys will take the iron throne
... but that might be a bit too straightforward for Game of Thrones. I expect there will be some unexpected twists...
Yeah, NO SPOILERS. I have the first two episodes, but I'm not going to watch them until Mrs P joins me, so we can watch it all together....... fingers crossed.
