"Hey , women cant train!" Some Sewards son had shouted at you , causing both Jace and you to beat the kid red and blue with your training swords . No-one tried stopping either of you , not even Jace because they all knew you where a formidable swordsman to rival Aemond . When Jace finally pulls back from beating up the kid , he puts his hand on your shoulder

"Dearest sister of mine , I think you'll kill him if you continue ."

"You wanna be next ?" You grunt

"Nope."

He steps back immediately , letting go of you , proud of being your twin.
