Remember the horror during Game of Thrones' Red Wedding scene? Everyone was shocked! And if you don't want to see those images once again, we suggest you skip this post entirely.

His heat rate seemed solid and steady for most of the episode, until the horror starts that is. Check it out below in its entirety and bonus horror scenes of the actual Red Wedding scene happening in GIFs below.
