So Game of Thrones is known for breaking hearts and killing characters, but one death no one saw coming was that of Hodor, the sweet, possibly part-giant who has been taking care of Bran Stark since he became paralyzed. Now, the fans have never been told very much about Hodor's past, especially why the only word he can say is "Hodor." In the episode aired on May 22nd, we learn a lot in a short amount of time. For one, Hodor got his name because Bran Stark warged into him from a vision, and something went wrong, resulting in poor Hodor essentially losing his mind while repeating the phrase "Hold the door" until it mushed together into "Hodor." The episode ends with Hodor holding the door closed while Bran and Meera escape from White Walkers...that were lead to them by a mistake made by Bran.

Bran Stark has a reputation of doing exactly what he is told not to do at exactly the wrong time. For example, in the first episode of the series, Catelyn Stark - Bran's mother - tells him not to climb around Winterfell anymore, and he "promises" not to. However, by the end of the same episode he is climbing one of the disused towers, stumbles upon #Lannicest (Jaime and Cersei) and gets pushed out a window, ultimately losing the use of his legs. This time, the Three-Eyed Raven tells Bran not to go into visions alone, but he does so anyway. This ends with him running into the Night King who can see and touch his otherwise invisible vision self. Because the king can touch Bran, he is able to mark him and somehow from that he can access the cave of the Raven. In the end, Bran loses his protectors, teacher, direwolf, and Hodor. Out of all of these Hodor is the most painful loss because he has been with Bran the longest, and has been Bran's legs for years. Until this incident, Bran's screw ups have only directly affected him. All other effects have been because of the aftermath of the results.

Hodor dying might just be what it takes for Bran to understand that when he doesn't listen to his teachers his arrogance effects everyone. So, even though it's painful that Hodor died in the way that he did, it may be what was needed to move Bran's development along. However, with all that being said, this is still the truest reaction to #HoldTheDoor:
