The Hound, if still alive (as the speculation goes . . . I tend to agree) isn't with Arya anymore. So there's nothing stopping him from having his own story separate from her. I think it would be really cool if he actually ended up protecting Sansa. He's in the general area, if the speculation is right. Maybe he'll team up with Brienne (who, as the speculation goes is still alive, too. Man these fake deaths are starting to get old). Maybe they'll even fall in love. Butt-ugly woman and burnt-ugly man, both on a mission to save the children. Nice fit.

As long as we get back to Jon and Tyrion, that's all that matters to me. There aren't many characters left to cheer for. Bran would be a nice addition, too.
