The latest Game of Thrones episode (s04e04: Oathkeeper) gave us new information about the Others. Obviously this is something George R. R. Martin has told David and Dan, and it's part of the new information GRRM is about to give us in TWOW, when we will get to know the Lands of Always Winter. In this night's episode, Kraster's lastborn son is left in the snow as a gift to the Gods, as we have previously seen in season 2 (and ACOK). This time however, after the Other/White Walker takes the baby, we follow them far north where a mountain and some northern lights are visible in the background. The baby is left in the center of some sort of "Ice Stonehenge" as another White Walker aproaches, takes the baby and with a finger touches his skin, turning the baby's eyes' color to blue, the blue eyes of the Others. So we get that the Others have the power to turn living humans into their own kind. This raises questions like: Is this the only form of reproduction the Others have? If the answer is yes, do the Others need humans to survive or just strenghten their numbers? Are they imortal (we know they can be killed by dragonglass and as we imagine, dragonfire and valyrian steel, but are they subject to decay?)? Are they just another race with their own culture and religion, or are they demigods or something?
