Some questions after the finale (spoilers alert).
What will Jon/Daenerys do when the discover the awkward truth?
Will Daenerys agree that it should be Jon, the rightful heir, who attempts to take the throne?
Will Jaime (and Bronn) head up North to reunite permanently with Tyrion?
Will Samwell be arsed when Jon/Daenerys turn up at Winterfell and she says she burned his dad/brother alive? I know he hated them but will he be happy to be on her 'side'?
Just how can Theon get Yara back off Euron and his fleet?
I think Jon will either pass up the opportunity to sit on the throne (remember he didn't want to become "King in the North", it was thrust upon him) or they will rule, if they are successful in battle, jointly as King and Queen as Targaryens can marry within their own family although I concede that culturally, it might seem a difficult thing for Jon, raised as a Stark, to comprehend.
I think Sam, with stealing the family sword, is past beyond caring for the males in his family. The females, however, are still close to him.
I think Theon will save Yara but ultimately die doing so, the full circle of redemption.
Then Yara will avenge Theon with the death of Euron.
The Hound will fight his brother and just as The Mountain is about to deliver the fatal blow, Arya will appear and take The Mountain down saving The Hound. With this, she'll spare him from her Death List given that she left him once to die and also that they are now on Jon's team together.
These are just my own opinions.
Other theories suggest that Jaime will kill his sister, The Queen Cersei.
I really really hope that Daenerys / Drogon face off mid air against The Night King / Viserion. Now, this would be a fucking epic battle, the real Ice v Fire.
