Game of Thrones season 7: 3 intrigues to explain the surprise return of SPOILER

A few months before the broadcast of the season 7 of Game of Thrones, one wonders how SPOILER could come back in the series. Watch out for spoilers!
The days pass and bring us slowly but surely of the return of Jon Snow, Daenerys Targaryen and the others. So we wondered if there is little some characters were trying to capture a White Walker in season 7 of Game of Thrones , it is now for other spoilers we are interested. Be careful, that those who do not want to know will not go further. According to Winter is Coming, David Bradley may be back in the next episodes. But David Bradley is none other than the interpreter of Walder Frey, we have clearly seen to be slaughtered by Arya in Season 6 of Game of Thrones . Faced with this mystery, we propose three scenarios that could explain this surprise return. The first possibility is the same as that which had already concerned Charles Dance, alias Tywin Lannister or Joffrey and Myrcella Baratheon. The Frey could organize a funeral with an open coffin, which would necessitate the presence of David Bradley.
The second option is a little more thrilling: Walder Frey could be part of a vision of Bran Stark. Indeed Bran has the ability to delve into the past and since Walder Frey has lived a long and busy life, it may be that his story is explored in the next episodes. Whether it is his involvement in the Red Wedding and his tragic conclusion to the Stark or his shenanigans with various personalities of Westeros, there is probably something to do with this character. It remains to be seen, in this case, what would be the use of such a flashback in the overall plot of the series. Finally the possibility that we like most is related to Arya Stark. The girl followed the drive of Stand-face Braavos and therefore wondered whether it might not simply steal the face of Walder Frey and impersonate him to continue to remove names from its list . Revenge is his first motivation and hiding in the guise of Walder Frey could make it easier for him. In short, the possibilities are numerous and we will have the answer only this summer. Waiting until then, we wondered if the season 8 Game of Thrones would be longer than expected . And you what do you think ?
