For me, one of the most impressive episodes of serie. I am not fan of GOT. I ignore many from the seasons because it seems only a too delicate balance between a childish story, admirable characters and high technology. This episode is , maybe, an exception. Because, in my case, it is the episode of one story- Hodor's. The explanation of name. The sacrifice. The expression of high duty becoming himself.Sure, the episode is source of many revelations. But the scene of the terrible pain, the end of a long effort for protect young Stark , the last trait of a not so significant character remains terrible in profound sense. So, a great episode.
