Game of Thrones fans reckon they’ve figured out the truth behind Ayra’s white horse

There was actually some foreshadowing earlier in the episode, with a little girl that Arya was trying to save was carrying a toy white horse. Symbolism, or a coincidence? There's also a pretty big theory that the white horse is a biblical symbol proving that Ayra is death.

Death rides on a white horse...oh yeah. Arya Stark is coming for the Mad Queen. #GameOfThrones pic.twitter.com/FU6y1Nq0n0

In Revelation 6:8, which tells the story of the Four Horsemen of the Apocalypse, a passage reads: "And I looked, and behold a pale horse: and his name that sat on him was Death, and Hell followed with him. And power was given unto them over the fourth part of the earth, to kill with sword, and with hunger, and with death, and with the beasts of the earth." This actually makes a lot of sense, when you consider Ayra's affiliation with death throughout the entire show. So basically, people reckon that she mounted the horse to ride off and kill Dany. There are also people that think the horse was Bran coming to save his sister (he can control animals, remember?) I suppose we won't really know until next week!
