This is my first fanfic on the site, I decided to do this fic because I always thought how different the series would have been IF another Lannister child of Tywin and Joanna existed.
So I created Jason Lannister, to non-book readers of A Song of Ice & Fire.
Joanna Lannister did have a father named Jason, so she named her second son after her father in this AU.
Jason is one younger than Cersei and Jaime and six years older than Tyrion.
If you want to know, how I imagined Jason would look, picture Antony Starr from The Boys just with green eyes.
Jason Lannister POV.
No words can describe the rage burning deep within Jason Lannister, due to his idiot of a man he calls father, had his little brother Tyrion Lannister arrested for Joffrey's 'murder'.
No fucking way his spoiled shit of a nephew was poisoned.
If Tyrion were to kill Joffrey, his little brother wouldn't have done it with poison.
No his little brother would have preferred to do it with his bare hands or even with Joffrey's sword 'Widow's Wail' and he would have helped his brother dispose of the body or make it look like it was the common folk who killed him.
Not like they didn't want to kill the little shit and hang his head on a wall at some whorehouse.
He could have killed some common folk too, to cover the tracks so his idiot sister wouldn't suspect them.
Seven hells he and Tyrion often spoke of this during the early part of the War of the Five Kings, they even wrote a full proof plan on how to get away with it if Joffrey went to full Aerys 'The Mad King' Targaryen II.
Such a shame Tyrion has too much of a heart to have done it, his little brother is the only one out of the family to have inherit mother's kind gentle heart.
Something his sister and father often mocked him as if it were a weakness, Jason has thoughts of doing the realm a favor and throw them both off the Red Keep to save the realm of their idiocy.
Truth be told, his now dead nephew truly is; correction WAS a cunt, which was no damn surprise on how the little shit turned out.
Considering who spawned the wretched bastard out of her cunt.
Speaking of which, his sister Cersei always hated Tyrion, blaming him for the death of their mother Joanna, remembering the time he struck her with his right hand after catching her twisting Tyrion's penis in front of Prince Oberyn Martell.
He never forgot the look on both of their faces that day, ofcourse his sister ran to father and he was punished for it while she got away with it.
All because father was grooming her to be Rhaegar Targaryen's bride, he wonders if their mother would proud on how her three 'golden cubs' turned out.
He is still furious at his father forcing him to wed Sansa Stark.
The poor naive girl had suffered enough as it is from their family has to done to hers, the fact she is nearly two years younger than his own daughter Joanna is down right sickening.
He is not some sick fuck like Walder Frey, reminding him to kill the old manand the entire Frey house for what they did to his son Tytos, the dimwitted weasels gouged out his son's right eye at the Red Wedding.
Atleast he prevented Sansa from being smuggled out of the capital by whoever the idiot lackey who was hired by Littlefinger.
He may not like the marriage between him and the young girl, but he would prefer having Sansa with him than Littlefinger, he made sure to hire men who are loyal only to him and him alone to guard her.
Ofcourse the damn weasel or 'mockingbird' he proudly called himself fled to the Eyrie, honestly Brandon Stark should have done the realm a favor and killed the bastard.
Not wanting to dwell on the thought for too long, he begins marching to the black cells where his brother is being locked up.
Only to be stopped by his idiot older brother Jaime 'The Kingslayer/Sister-Fucker/Attempted Child-Murderer/Kinslayer' Lannister, who looks speechless to see his other little brother.
"Jason, what are you doing here?" Jaime asked his brother in shock, Jason rolls his eyes at his brother's question.
"To congratulate Tyrion in person ofrcourse." Raising his arms up for dramatic purposes and to annoy his idiot older brother who could only look at him with a raised brow.
"Congratulate him for what dear brother?" Jaime asking rather nervously on Jason's question, making him sigh.
This never never amazed Jason on his brother's stupidity at times, if he, Tyrion and Cersei can have one thing in common is that Jaime is the idiot out of the four siblings.
"For killing Joffrey ofcourse dear brother; wish I could have had a part in it too. We could have gotten away with it too." He answered his brother with a gleeful expression, seeing Jaime's distraught face turned to anger made the moment even more sweeter.
"Joffrey was our King brother, have some respect for Cersei's son." Jaime defenselessly says to him, but Jason can see the anger in his brother's eyes, Jason knew Joffrey, Myrcella and Tommen were his brother's children with Cersei.
"Like Cersei giving the same respect when my son was captured because you got your ass handed to you by Robb Stark. I mean seriously Jaime, has Cersei's cunt turned you into such an idiot, did Cersei literally fuck your brains out?".
He mockingly says to Jaime, the shame in his brother's eyes said it all, even seeing his brother clench his fist on his remaining hand.
"Did you come all this way just to mock me brother?" Jaime says to his brother, trying to keep his anger together.
"Is it not my job as your little brother to annoy the absolute seven hells out of you?" He playfully jests his older brother, seeing Jaime struggle to contain his emotions made Jason grin.
"If you came here to mock Tyrion than it is wiser you leave Jason." Jaime hissed at him, oh the lion is FINALLY showing his fangs.
"You wound me dear brother, perhaps the only time you ever will. No, I am not here to mock Tyrion, unlike you Jaime. I would never hurt our brother in such a way as you and father did to him with Tysha." Jason snapped back by bringing up the 'Tysha Incident'.
Once he heard about the incident from his Aunt Genna, he nearly wanted to murder both his father and brother on the act, he did break Jaime's nose that day as a reminder to never hurt Tyrion ever again.
"Don't EVER bring that up Jason." Jaime snarled at him with anger in his voice.
Jason smiled at this, it was so much fun when Jaime and Cersei lose it.
"Why? Is it because Tyrion truly saw you for who you truly are? That you truly are father's son?" He quipped back to Jaime, his brother actually looked insulted on the 'father's son' remark.
So he decided to continue speaking for he really wanted to put his idiotic brother in his place.
"Atleast I honored mother's memory by being there for Tyrion as a true older brother should be for their little brother. Something you clearly forgot. Just like you forgot about Princess Elia and her children." Jason snapped back at his brother.
Seeing Jaime look so hurt really brought joy to Jason, it was a shame really on their paths came to be.
He and Jaime were once close when they were young, the best of friends they once were, remembering the days Jaime use to teach him how to swing a sword; their dream to become the greatest knight's of Westeros has ever seen.
That all changed when their mother died, Jaime defending Cersei for her treatment of Tyrion and leaving him to suffer and practically raise Tyrion for their father despised his little brother.
Jaime getting trained by the likes of Ser Arthur Dayne, while he was stuck with their brooding Uncle Tygett who died from the fucking pox.
Jaime is their father's 'golden boy', who could do no wrong in his eyes, even stabbing Aerys Targaryen in the back for their father and sitting there on the wretched iron throne, while Elia Martell.
A woman who treated Jason with kindness when he visited King's Landing and the only one in his family to have liked the wife of Prince Rhaegar Targaryen.
Only for her to get raped and murdered by Gregor Clegane, after he bashed her son's brains to the wall and for the idiot Armory Lorch to stab Princess Rhaenys half a hundred times, he's grateful to whoever killed Lorch.
Sadly what was the final nail in the coffin that ended any relationship between the two brothers was the incident with Tysha.
Jason could never find it in his heart to forgive Jaime, not after what their father made Tyrion witness what he did to Tysha, he had nothing but resentment and hatred towards Jaime from that day on.
He never saw how Tyrion could forgive Jaime for his involvement in the deed, atleast Tyrion grinned at seeing him break Jaime's nose in the courtyard that day. And ofcourse Jaime's involvement of helping create and bring Joffrey into the world.
Jaime took a deep breath, Jason saw his brother looked rather hurt from his words.
Since when did Jaime fucking Lannister have a heart.
"Why must you torment me Jason? Have I not suffered enough as it is?" Jaime asked him as if he was whispering, Jason scoffs at this.
"Because you fucking deserve it for being Cersei's bitch. This stupid war wouldn't have happened if you kept your fucking cock out of Cersei's cunt. Maybe you would still have your hand or I don't know make our House look like a damn joke." He snarls back at his older brother, Jaime tensed upon hearing his words.
"You speak as if you are better than us little brother and yet your cruelty shows no bounds." Jaime adds to the comment.
Jason grinned at his brother's words, good he was waiting for Jaime to bring this up.
"Unlike you, Cersei and Father dear brother, I have a heart when it comes to others. Honestly father spends so much time hating Tyrion and say he would bring our house to ruin with his 'shame'. And yet he cannot see it will be Cersei who will bring our house to ruin if she remains in power." Jason getting up and personal to his older brother.
Pinning him to the wall with both of his hands grasping Jaime's collar.
"Get out of my sight, so I can have a proper visit with my only true brother." Jason pushes Jaime out of his way causing him to stumble back, but not before looking down on him.
"To think I once looked up to you more than anyone else in my life. Now all I see is nothing but the family's biggest disappointment in my eyes.".
He hissed at Jaime, who was hurt beyond words after he told his brother this, before Jaime got up and walked away.
Arriving to his brother's cell not long later, he can see Tyrion looking at him with such a disappointed look on his face, he never understood why he would defend Jaime.
"You are too harsh on him." Tyrion simply tells Jason with a matching disappointed look on his face, making him roll his eyes.
"He should be grateful I only broke his nose after what he and father did to you." Adding to the comment, he knew it was a low blow to his brother, but he will never allow Tyrion to defend him.
"Why are you here?" Tyrion asked sadly to him, Jason kneels down to his little brother and wraps him in an emotional hug.
"Because you are my little brother. I promised mother to always be there for you. I will not fail her as they did." Jason firmly says to his brother, Tyrion smiles upon hearing this and it made Jason smile even more.
Only people who can ever bring true happiness to Jason Lannister are his daughter, his son and Tyrion, Myrcella and Tommen are debatable at times.
It really depends on his mood.
"Thank you Jason...I knew I could always count on you." Tyrion softly says to Jason, making the elder brother smile back trying to keep his emotions in after hearing this.
"I love you little brother. I'll fight tooth and nail for you, you know that right?" Jason says to his brother, Tyrion smiles with a nod.
"Ofcourse Jason..but for how long? Father and Cersei want my head for a crime I didn't commit." Tyrion puts his head down in shame, this infuriated him for how cold their father and sister have treated him.
Jason sat there, not knowing what to do for a good few minutes, they sat there in silence until his eyes widen with a look Tyrion knew all too well.
"Fuck don't tell me you got a plan dear brother, no offense but you are only the second smartest out of the four of us siblings. And that is sadly not saying much." Tyrion says to Jason, breaking the silence between the dark cell.
"Alteast I am above Cersei and Jaime." He optimistically says to his little brother in a childish manner, Tyrion couldn't keep a straight face for he burst with laughter.
"You are correct dear brother. You are above Cersei and Jaime, so now tell me brother. How do you plan on freeing me from the 'crimes' Cersei and father accuse me of such?" Tyrion says while gesturing his arms up in the air to show Jason the chains.
Jason smiles for a moment before answer his brother in a serious tone in his voice.
"I'm going to tell father you demand a trial by combat for your innocence and I will be YOUR champion little brother."
After saying this to Tyrion, who remained speechless upon hearing Jason's plan, only began to worry Jason who could only cock a brow in worry, but before he can say anything back to his little brother.
Tyrion awkwardly hugs his brother, Jason accepts the hug, he can hear his brother's muffled cries echo throughout the cell and all Jason can get from his muffled words were only.
"Thank you brother."
The End of Chapter One.
I was going to end it upon Jason and Tyrion meeting in the cell, but I changed it last minute and felt it would be better ending the chapter with Jason coming up with the plan.
Chapter 2 will be a three POV chapter between Joanna, Jaime and Jason.
