What if Robert Found out about J + C (Spoilers)

[IBSXYPNTS]

Just as I played the Fire and Blood Mod I was wondering what everyone thought would happen if King Robert ever found out about Cersei and Jaime. I personally think he would have them killed. However this also brought up the question, what would Tywin do if faced by this? Is he aware of their incest? Would he be forced to allow his children to be put to death or would he somehow fight it out with the Iron Throne?

Most of all I was curious how this would affect the situation in Fire and Blood if an event appeared with Robert discovering the incest. With the Targaryens attacking the last thing the Iron Throne could afford is its strongest supporters becoming the enemy.

Your thoughts?

Robert would have gone absolutely insane - Ned tells Cersei to flee across the narrow sea to escape Roberts fury.

I think Tywin, deep down, knew about Jaime + Cersei, but supressed his feelings on the issue for the sake of House Lannister. What's he gunna do? Send Jaime to the Wall, Cersei to the Silent Sisters, and leave Tyrion as his heir? Don't think so!

I think Kevan was aware of it.

[Mikail Mengsk]

He would have sent the Royal Guard against Jaime, and personally beaten Cersei to death.

Then, the Lannisters would have rebelled, but Robert's charisma would have kept the Kingdom united. A possible outcome would have seen the Lannisters losing their powerful position, maybe replaced in Westerlands by another House.

Problems would have arisen concerning his "sons". I can see him killing Joffrey in a burst of rage, but not Tommen and Myrcella. Their claim to the throne was, at that moment, null, so they wouldn't be dangerous for him. He would have chosen another wife and made other heirs.

[Mount Suribachi]

We know Kevan was aware of it - he tells Jaime as much in AFFC. How early he was aware of it is the question.

[Pinkie Pie]

Tywin would not have risen up against Robert, he is not stupid. He would use his wealth to an advantage and probably have Robert assassinated.

Robert would have ended up marrying Maergarey Tyrell, even before his death plans were being made for such an outcome and this would help give him a strong ally in the Tyrells to replace the Lannisters.

It is a source.Renly was plotting to marry Margaery to Robert.

''A year ago I was scheming to make the girl Robert's queen."

Along with the above quote there is also a hint when he asks Eddard Stark if Maergary Tyrell reminded him of Lyanna Stark and is saddened when Eddar states that she does not.

[DarthRuanek]

Assuming they didn't escape, Jaime and Cersei would probably die. Jaime could go to the wall, but Robert probably wouldn't want that, and Jaime probably wouldn't, either. (I doubt he'd want to take more vows.)

I'm not sure what would happen with the children. Robert doesn't seem to have a large amount of affection for them, but Joffrey was his heir. They wouldn't be a threat to his claim if it was announced that they were children of Lannister incest, so they wouldn't need to die.

Tywin probably wouldn't rebel. Baratheon would have Stark and Tully support for sure, and through diplomacy could probably get Tyrell (Robert needs a new queen, after all). The Vale, Dorne, and the Iron Islands would be more likely to stay out than support the Lannisters. Really, Tywin's biggest chance is if he gets the Tyrells to join him, and he can't offer nearly as much as Robert can. It would be slightly awkward given his campaign in the Riverlands, but I think he would pull out to salvage as much as possible.

Tywin would probably lose all potential heirs from Cersei, but he may have accepted that after Jaime joined the Kingsguard. He'd probably pass Casterly Rock and the Westerlands to Kevan and his line (Lancel). He certainly wouldn't give it to Tyrion. Given Robert's unwillingness to make Robert Arryn Warden of the East, I wonder who the new one would be with Jaime gone.

As for whether Tywin knew about the incest already - Kevan certainly did in a later book, but at this point it's hard to be sure. If Stannis sent out a letter with the information, he'd at the very least consider it given the evidence Ned and Jon Arryn uncovered. But it's hard to say whether he knew before that. He may have known of Jaime and Cersei's affection for each other.

There's a bit in GoT where Renly asks Ned to look at a picture of Maegery Tyrell, who he believes looks much like Lyanna Stark. Renly already had plans in place to have Robert marry Maegery once Cersei was exposed.

EDIT: ...and PinkiePie beat me to it.

[mcotrone]

in a games of thrones the first book "renly takes eddard aside to show him a picture of Margaery, pestering Ned to say that Margaery looks like lyanna; Ned insists she looks nothing like his late sister. Ned believes this is ironic, that perhaps Renly, a young Robert look-a-like, believes he has fallen in love with a Lyanna look-a-like. Instead, it seems to be part of a Tyrell plot to get rid of Cersei and put Robert in Margaery's path. Indeed, moments later, Robert tells Ned that Renly has been telling him about Loras's sister."

[IBSXYPNTS]

I dont know if Tywin would have risked the entire Lannister position on fighting the inevitable outcome. I think he would rather have his son and daughter die and a next of kin Lannister take over after his death. From what I gather of his personality he seems more concerned with the name of Lannister as a whole vs family. Im sure Robert would have married Maergarey and then maybe due to the loss of power Tywin would have acted on the actions taken against his family.

[Prophet1331]

I don't think Tywin would forgive Jaime's death as easily as Cersei's or Tyrion's. Though before all going all out against Robert he would consider all possible options. It wouldn't surprise me if he'd join the Targaryens in an attempt to regain the house' position. Few chances for the Targaryens having them after all that happened however. Safe to say if Robert found out, House Lannister would have lost almost everything.

Nice topic though at first I misread it and thought about what would have happened if the Jon = Rhaegar + Lyanna turned out to be true and Robert found out. That would be a big strain on the Stark and Baratheon relations.

Well thats a completely different discussion bahaha I think that with Tywin wanting revenge he would try and aid the Targaryens as you suggest but the thing is would they agree to help the man who killed their family? I am on the fence there. Tyrion would become the heir to Casterly Rock but Im sure that Tywin would in some way make it so he took the Black to make up for the crimes of his brother and sister by defending the realm.

[Prophet1331]

Well if Joffrey, Tommen and Myrcella were hurried away from King's Landing than Tywin could claim Robert has gone mad due to Targaryen blood or something and support Joffrey in a war against his father. That way he would have something to offer to the Tyrells, but it would be a long shot (why would the Tyrells fight a hard battle to make a queen when they could fight an easier one giving Robert one), however if he pulled it off you'd have Robert with the Stormlands, North, Tully and maybe the vale against Joffrey backed by Tywin the rich Westerlands and the fertile Reach

[Pinkie Pie]

You are forgetting one major detail with the Reach, Mace Tyrell follows Loras Tyrell (as proven when he chose to crown Renly) and Loras follows Renly and Renly wants Maergary to wed Robert.

Mace Tyrell would have almost definitely joined the Baratheons once Cersei was removed.

[jomas]

If his children were removed, it would be interesting to see if Tywin would have assassinated him, then it would make Stannis king.
If Stannis and Tywin got friendly, I think it would be an incredibly tight-shipped kingdom, I think they could beat back Danny and any threat in the north rather easily.
Although I suppose Stannis wouldn't allow that, family first and he'd have a general mistrust for Tywin (rightfully so).
