Every Single Major Death We've Seen in Season 7 of Game of Thrones

It's true, a few men from the Brotherhood Without Banners die during that insane mission beyond the Wall. One gets totally mauled by a zombie bear and another few get wrecked by wights. The important loss, though, is Thoros of Myr. He suffers a pretty rough attack by the above-mentioned zombie bear, and though Beric cauterizes the wound with that flaming sword, Thoros is so weakened that he freezes to death in the night.
