So as anyone who has read the source novels will know, these are in fact the final three Stark kids being burned alive...Ok, not really -- they're actually just three hapless prisoners being sacrificed to appease the "Red God", so that Stannis Baratheon might one day be king. There doesn't appear to be any principal cast members visible in the pics below, but we assume both Carice van Houten (Melisandre) and Stephen J. Dillane (Stannis) are around somewhere.
