Game of Thrones season 7: The death of a character spoiled by the promo pictures?

Season 7 of Game of Thrones only arrives in a few months but did the first photos unveil the death of SPOILER?
July 16 is getting closer and that’s why we’ve recently been offered a general recap of all the spoilers on Season 7 of Game of Thrones story to know a little about what to expect. Today we come back with new possible spoilers that are related to the fate of a particular character: Gray Worm. The first promotional photos unveiled some time ago by HBO show us among others Gray Worm in company of all the small restricted board of Daenerys Targaryen: Tyrion Lannister, Missandei and Varys. First of all, Daenerys, Missandei and Gray Worm wear leather clothes that look warmer than what they used to wear. In other words, it’s winter is coming and it’s time to stand out the winter coats and cover up to deal with the cold wave that’s going to hit Westeros. But if we look at Gray Worm more closely, we also notice a new Targaryen brooch, different from the emblem of the house that we know so well .
The three usual dragons’ heads are placed on a circle, which offers a sympathetic variant of the Targaryen sigil while recalling the existence of the three dragons of Daenerys: Drogon, Viserion and Rhaegal. This pin is undoubtedly a sign of confidence and the position of Gray Worm within the army of Dany, yet we find the same on the pass of Missandei on another photo promo. This may mean two things: either Daenerys gives the same emblem to his faithful counselor, or Missandei has inherited the spit after the possible death of Gray Worm . As a reminder, the Unsullied should attack Casterly Rock in season 7 and it is possible that it does not survive and that Missandei carries its brooch to pay homage to him, Especially since the photo on which it can be seen shows her with a rather sad face. In short, all this to say that we are not reassured about the future of Gray Worm but that we hope to be wrong. While waiting to know its destiny, discover the salary of the actors of Game of Thrones, become the best paid TV ! Do you think Gray Worm can die in season 7?
