One of the clear highlights of the GoT season seven finale (apart from Littlefinger taking a big whiff of the sweet smell of justice) was Jaime Lannister (Nikolaj Coster-Waldau) finally walking away from his sister/lover/queen. 

Quick recap: After Cersei (Lena Headey) reveals to her brother that she has no intention of sending her troops up north to fight the Army of the Dead (despite saying she would), Jaime tells her she's lost her damn marbles. Cersei threatens to kill him (yes, her own flesh and blood) and almost does, but it seems she may not be completely devoid of a sensitivity chip and can’t bring herself (or rather, Ser Gregor) to go through with it. Cue Jaime’s look of utter betrayal and disgust (and audiences screaming out, “Yaassss Jaime! Know your truth!”). He then gets the heck out of Dodge King’s Landing, but where is he going? Here, four likely Jaime Lannister theories explained.

Jaime Is Joining Forces With Jon Snow and Daenerys Targaryen

Jaime's look of revulsion following Cersei's confession that she was bluffing about her promised truce, leads us to believe it's highly likely he will join Jon Snow (Kit Harington) and Daenerys Targaryen (Emilia Clarke) in the North to fight the Army of the Dead. One of the final things we saw during last night's finale was Jaime slipping a glove onto his golden hand, which could be because he knows that he’s a persona non grata up North and needs to disguise himself (or you know, because it’s winter). If this theory pans out, it would mean that Cersei has lost both her brothers to her biggest enemy. Oh, snap.

Jaime Is the ‘Prince That Was Promised'

According to the prophecy, the ‘Prince That Was Promised’ (who may or may not be the same person as legendary warrior Azor Ahai) will come and save the world from darkness. Most assume that this Promised Prince is from the Targaryen bloodline, which is why many think that the prophecy is referring to Daenerys (the Valyrian translation could be “prince” or “princess”) or Jon Snow (who is the child of Rhaegar Targaryen). Some also hypothesize that Tyrion could be the Prince since it suggests that he is the spawn of the Mad King, Aerys Targaryen, and Joanna Lannister (Joanna and Aerys are rumored to have had a torrid affair). But what if Cersei and Jaime are the children of the Mad King and Joanna? It would certainly explain their blond locks and affinity for incest (two very Targaryen traits). If so, then Jaime could be the 'Prince That Was Promised.' Whoa is right.

Jaime Becomes the Night King (Slayer)

Hey, he’s already slain one king (i.e., Dany’s dad, the Mad King), so this doesn’t seem too outlandish of a theory. Jaime has mixed feelings about his Kingslayer rep, so going after the Night King could be a way for him to redeem himself, and simultaneously go down in Westeros history as more than just an incestuous backstabber. But if this does happen, then the question becomes, will Jaime survive a brawl against the Night King? And if the Night King dies, do all the wights die, too? Because that would be super convenient for everyone.

Jaime Kills Cersei

A major prophecy in the Game of Thrones books says Cersei will meet her maker at the hand of the Valonqar, which is High Valyrian speak for “little brother.” Most GoT fans assume this is referring to Tyrion since he’s both younger and physically smaller. But here’s the twist: Jaime was born shortly after his sister, meaning he could also be the Valonqar. Yes, he loves his sister, and they made children together (never not going to be ew), but Cersei is straight up cray. Judging from the season seven finale, Jaime appears to finally realize his sister is a maniacal tyrant and she must be stopped.
