Game of Thrones director Mark Mylod recently told IGN that showrunners David Benioff and Dan Weiss had no discussions with him regarding Lady Stoneheart (resurrected Catelyn Stark):
“I’m not in the writers room, and I can honestly say, hand over heart, that I have not had one discussion about Lady Stoneheart. So I have no idea what’s going on in David and Dan’s minds.”
“I’ve genuinely had no discussions about Lady Stoneheart, so I genuinely couldn’t comment about whether that might or might not be in their minds for the future.”
Mylod has been with Game of Thrones for 2 years now and also directed episodes 7 & 8 of season 6 which marked the return of Brotherhood without Banners (Stoneheart leads this group in the books after Beric Dondarrion gives his life for hers). So unless this is another ‘Jon Snow is not coming back’ kind of ruse, Mylod should have probably known if the writers had planned for Lady Stoneheart’s appearance on the show. And after the return of Beric in episode 8, this statement from the director is yet another setback for fans who were hoping to see Catelyn back on the show.
