It's really getting close to time to wrap things up.
Does anybody know if they are planning to leave any of this for next season?
We'll have Sansa's wedding next week and the RW the week after that.
The Purple Wedding won't be in this season. No reports whatsoever of it having been shot, as opposed to the RW. Also, no Dornish in King's Landing this season, and you can't have the royal wedding without all of your (still loyal) vassall states present.
Especially after Joffrey just whored his sister out to Dorne, the least they could do in return is to attend his wedding.
No wall war either. The actor who plays Pyp (who stayed at Castle Black) said he only shot one scene this season. Which means Jon's arc will most likely end with him returning to Castle Black in his final scene.
I also think we've seen the last of Jaime and Brienne this season. Their next stop in their story is King's Landing but they don't arrive there until after the PW.
