Jon and Daenerys might be the more dramatic, destiny-fulfiling pair, but Jaime and Brienne have given us major feels since season three. Brienne is the one person that has a real connection with Jaime (other than Cersei), and she's also the only one who knows the truth about how Jaime earned his infamous nickname. It's easy to see that Brienne has feelings for Jaime, but there's always been a Cersei-shaped object in the way of Jaime coming to terms with how he really feels about Brienne.
That object is out of the way, since Jaime peaces out of King's Landing for Winterfell at the end of season seven. Will their close proximity fighting for the good guys finally push them to confess their feelings? The season eight trailer reassures us that Tormund survives Viserion's attack at Eastwatch — will his brush with death make him proposition Brienne before Jaime can get a word in?
