Well, it seems you will have to wait until season 6 of Game of Thrones to see what happens to Bran, Hodor, Meera and Summer (Jojeen Reed sacrificed himself at the end of the season). Last we saw the gang they had crossed The Wall and found the 3-Eyed Raven that has been in Bran's visions since season 1. Now Hodor himself Kristian Nairn spoke with Yahoo! Australia revealing that the gang won't be appearing in Season 5 at all:
"We have a season off and we have a year's hiatus, solely because I imagine our storyline is up to the end of the books. So, I get my year off now to do Rave of Thrones and gallivant all over the world."This isn't the first time we seen an entire storyline not be utilized in the show. Season 4 didn't even mention what happened to Bran's younger brother Riccon.
