I heard that the first person lined up at 4 am and by 10:30am the line was capped and people were told to return the next day. Although the wait was long, it was fun talking to die hard fans about the show. The main topic seemed to be "Jon Snow...will he return?" with the buzz being ...yes he will and Melisandre will resurrect him. Judging from all the "Kit Harrington spotted in Belfast articles", I would not be surprised if he does return but in a way no one will predict.
I cannot wait for Season 6!
