The first two trailers look relatively tame, with no major spoilers. However, in the third trailer dubbed "Aftermath," a scene showing Winterfell after the highly anticipated Season 8 battle don't show any sign of life. In fact, it shows the prized possessions of several main characters without their owners. 

First, fans noticed Jaime Lannister's golden hand, then the camera pans to Tyrion Lannister's pin, and finally you see Jon Snow's sword buried in the snow.
