She can always go on Project Free TV and watch GoT. That's what I've been using to watch Breaking Bad.
And yeah, some troll wrote Tywin Tyrion spoilers on the GRRM BB thread and his post got whacked. Unfortunately, I found out BB spoilers on Facebook about this past episode, and I'm only on season 3

As for Halloween costumes, I think Cersei and Dany would be the 'obvious' female costumes, but both are my least favorite female characters in the whole series.
I think a Red Wedding costume would be fun.
