Two Swords. This Sunday marked the return to HBO’s grimdark fantasy epic, A Game of Thrones. This season is based on the second-half of George RR Martin’s A Storm of Swords, book 3 in his A Song of Ice and Fire series. The first episode takes us through Westeros and the lands beyond the Narrow Sea, displaying palace intrigue, spoiled kings, Wildling cannibals and (of course) dragons. As usual, spoilers and then some.
