No fictional family has been synonyms with words like "diabolical," "manipulative," and "power-hungry" quite like the Lannisters have been. Although Tyrion is easily the most famous Lannister on HBO's masterpiece Game of Thrones, it's Jaime and Cersei who push boundaries the most. Therefore, they just stand out above the rest. In theory, we should absolutely loathe these two. This is especially true of the Queen Regent Cersei, who continues to make bad choices and never seems to learn from her mistakes. And yet, we often find ourselves relating to them and even caring about them. This says a lot given the fact that they have both been behind some of the most morally incomprehensible actions in television history. And that's no understatement.

Part of the reason that we can cut these two horrible people some slack is that we understand that they legitimately love one another. Of course, the fact that they're brother and sister does complicate things for us as it's a pretty icky hurdle to get over morally. None-the-less, we buy into their relationship. It's a redeeming factor for both Jaime and Cersei. But that's not to say that there aren't things about it that make no sense at all. This list will delve into some of the odder aspects of their relationship throughout the show's first seven seasons. Most of these entries have to do with some interesting story choices, but others have to do with issues behind-the-scenes. Without further ado, here are 20 Things That Make No Sense About Jaime And Cersei's Relationship.

Nobody Knew About Their Relationship

It's hard to believe that Cersei and Jaime Lannister kept the truth of their relationship under wraps for so long. It's really not until Bran stumbles across them in the very first episode that anybody starts to take notice. Sure, there were one or two people who knew, but they are small potatoes in comparison to the vast majority of people who had no clue whatsoever.

There's just no way that their tryst would go unnoticed in King's Landing or back when they lived at Casterly Rock. Seriously, when you think about how long they've been together and how few people seem to have been in the know about it, it just doesn't add up.

Robert Didn't Notice Their Kids Looked Like Jaime

Speaking of nobody knowing about Cersei and Jaime, are we really supposed to believe that King Robert Baratheon was so tipsy every night that he didn't notice his wife sneaking away on him? More importantly, how did he not see the resemblance between Joffrey, Marcella, and Tommen, and their "uncle" Jaimie? Robert knew that he fathered other children, all of whom had his dark hair. But somehow he believed that it was normal for his kids with Cersei to bare her looks.

To be fair, Robert was pretty removed from his kids. He was more interested in other pursuits. But still, the guy had to be completely oblivious not to have seen that his children weren't his own.

Their Kids Are Very Normal (For The Most Part)

In Game of Thrones, Cersei makes a comment about the Targaryen family, who were famous for their romantic relationships within their family. She stated that the gods used to "flip a coin" whenever a Targaryen was born to determine whether or not they would turn out okay. Well, this has a lot of basis in reality as bad things tend to happen when two people with very similar genes mate. Therefore, it's pretty odd that all three of Jaime and Cersei's kids turned out normal. Sure, Joffrey is sort of the exception to the rule. He was a total monster but he wasn't entirely crazy. He was more like a very spoiled little boy with a lot of power. And then there's Tommen and Marcella, both of whom are utterly normal despite having parents who are brother and sister.

Cersei Won't Be In The Same Room With Jaime's Right-Hand-Man

Some fans may not have realized that Cersei has never shared a scene with Jaime's right-hand man, Bronn, throughout the entire run of Game of Thrones. This is because Lena Headey (Cersei) and Jerome Flynn ( Bronn) used to date and their relationship did not end on good . As reported by The Telegraph, Headey and Flynn are not on speaking and have both desired to never be on set at the same time as one another. Yep, their dislike for one another truly is that intense.

Although they appeared to have patched things up sometime during the middle of the show's run, their current anger for one another is said to be as bad as can be. So, this will likely continue on in the final season of the show.

Cersei Blamed Jaime For Marcella's ing

Cersei tasked Jaime with bringing back their daughter Marcella from Dorne despite the fact that she was married off to the Martells in order to strike an alliance between the houses. Jaime was happy to go and save his daughter after receiving Marcella's necklace alongside an eery message. Jaime and Bronn managed to get her out but a vengeful Elaria Sand has other plans for her.

Although Elaria was ultimately the one responsible for the demise of the Cersei's daughter, for a while she actually blamed Jaime for it. This literally made no sense since Jaime did everything he could to save her. It seems like Cersei never really forgave Jaime for this as their relationship was never quite the same again.

Jaime Didn't Blame Cersei For Tommen's ing

Jaime had nothing to do with the demise of his daughter Marcella, but Cersei very much had something to do with their son Tommen's offing. Although Tommen made that final jump on his own, he was put in that position after his mom took out his wife, The High Sparrow, and a great deal of fairly innocent people. Jaime knew this and yet he didn't harbor resentment for it. Sure, he became more worried about his partner after the event at the Sept, but it didn't really have to do with Tommen.

Jaime should have been very angry at Cersei for what happened. Her anger and hurt outweighed her love for her son and that ultimately led to his demise.

Why Would Cersei Be With Lancel If She Loved Jaime?

In both the books and the show, Cersei Lannister has claimed to love her brother Jaime on multiple occasions. She remains devoted to him in multiple ways including only having his children. But she wasn't faithful to him when he was captured by Robb Stark. During this time she spent her nights with her cousin Lancel. This was an odd choice as Lancel had none of the qualities that Jaime did with the exception of being a Lannister and being blonde. She valued her family the most, therefore one could make an excuse for having relations with her own cousin over other characters. But in the books, her betrayal is even odder as she was with a character named Osmond Kettleback, who was not related to her.

Jaime Almost Had Cersei's Season Six Storyline

The Independent posted an article that included details of what George R.R. Martin had originally planned for his characters in A Song Of Ice And Fire. Martin explained that he once wanted Jaime to be the one to go on a rampage after the demise of Joffrey. Of course, in the show, it's Cersei who goes down this path. The books haven't quite caught up, so it's unclear how Martin will proceed with his work. But with what he's done with Jaime in A Feast For Crows, it's highly unlikely that he will take on Cersei's qualities.

It makes far more sense for Jaime to continue on a redemptive path while Cersei heads the other direction. Not only is it compelling, but it fits within what Martin originally set up.

Cersei Is Barely Jealous Of Brienne

One of the things that doesn't make sense about Jaime and Cersei's relationship is how Cersei wasn't all that jealous of Brienne of Tarth. Although Jaime and Brienne never had a romantic relationship, their connection is arguably deeper than the one between him and his twin sister. Cersei is smart enough to pick up on this which probably explains the slight hostility that she showed her in the few scenes that they shared together. But, then again, Cersei is pretty mean to everyone she comes across. It's odd that she didn't grill Jaime about his time with Brienne more, as well as go after Brienne in a more obvious way. After all, Cersei isn't one to let these kinds of things slide. She is very vindictive. And yet, in this scenario, she totally stepped back.

Jaime Didn't Receive A Warm Welcome When He Came Back To Cersei

When Jaime was captured by Robb Stark, Cersei spent much of her time trying to get him back to her. This was one of her main goals while he spent his time behind bars. And yet, when Jaime finally returned to her, she seemed less than pleased.

We can all that strange scene when he returned to her and she simply gave him a disappointed look. One would have thought that she would run into his arms. But Cersei seemed ashamed of Jaime for getting caught as well as losing his sword hand. This would make sense for Cersei's character if it had been any other character. But when it comes to Jaime, she's supposed to love him more than anything.
