Game Of Thrones: Season 7 - 8 Clues From "Stormborn" Trailer

8. Civil Unrest

A Targaryen is not to be trusted?! Do you even know who you're talking to, Royce?

Clearly, this is Jon laying out his plan to head to Dragonstone - probably in the wake of receiving Sam's raven about their stock of Dragonglass, and possibly also after being invited to swear fealty to Dany around the same time. He's still a diplomatic leader, seeking the approval of the Lords under his banner, but while they might voice their dissent, there's no way they will sway Jon when he knows the value of Dragonstone's bounty in the big picture.

This is probably where Littlefinger will find his opportunity to cause further unrest in Jon Snow's forces. If - as suspected - Littlefinger knows the truth of Jon's parentage, he could try and blackmail Snow, knowing his men have deep-seated resentment of Targaryens.

Or he might just flat-out tell them and deplete Jon's forces fatally, aligning with the disloyal Lords himself (along with the army of the Vale) and making a play for the North (again).

To his credit, Jon does not look impressed by Royce's insolence...
