I think they were people they had killed; as the girl that beat the holy cr@p out of the Stark girl ended up in the " big room full of faces " iirc when she cut out the candle and took to her training with that little sword. It's so engaging GOT, but if I'm honest I'm just wanting this big ass battle scene now, Dragons, Whitewalkers, probably the destruction of many cast members...
The amount of cash they get is nuts, someone told me around £2 million per episode. wow.
Breaking Bad; sensationally good.
