If Game of Thrones Season 5 had any notable crack in the facade, it was Jaime and Bronn’s ultimately arbitrary adventures in Dorne, a stand-in for a long-delayed book plot returning us to the Riverland Tullys. Now, evidence suggests Jaime may finally fulfill his literary destiny, running afoul of some long-missed book characters as well.

Take this with the usual Game of Thrones salt (note that salt and bread have poor recent history of providing protection), but Watchers on the Wall outsources a report from Los Siete Reinos, claiming that among other things, Clive Russell has been spotted reprising his role as Brynden “Blackfish” Tully, uncle to the late Catelyn Stark. The same reports also list Nikolaj Coster-Waldau and Jerome Flynn sharing scenes with the actor, ostensibly confirming that Jaime will take up the Lannister Siege in the Riverlands, a long-delayed book plot.

Russell’s character was last seen exiting the infamous Season 3 “Red Wedding” just before the slaughter, disappearing to whereabouts unknown, along with the wedding’s groom, Edmure Tully. Granted, Tobias Menzies might be too busy with Outlander to reprise his role as Edmure, it’s at least something to consider, if the Blackfish has returned.

Elsewhere of Game of Thrones Season 6, screen legend Max von Sydow has been cast as the mysterious Three-Eyed Raven to a returning Bran, while Deadwood alum Ian McShane will also appear in a limited, mysterious role, joining Richard E. Grant and The Babadook star Essie Davis as theatre troup players, four notable actors as the Tarly family, Melanie Liburd as a new Red Priestess, and Borgen star Pilou Asbæk as fan-favorite Euron Greyjoy. Apart from a list of directors, Of Monsters and Men will put in a cameo, and story logistics seemingly confirm scenes set at The Wall next year, presumably to explain this giant spoiler.

Well, what can we make of the latest Game of Thrones Season 6 sighting? Can we expect more official confirmation of the role before 2016?
