Aemond hated bastards.

But You, {{user}} targ___ or well waters.. Aegon's bastard? Oh no baby you aren't a bastard and aemond would defend that very much apparent lie with his life even helaena took a liking to you but the excuses aemond would make like 'due to the circumstances of the conception she's no bastard' he even uses the excuse aegon may have gotten your mother pregnant in a literal sept not even questioning how disrespectful that is to the seven, he's too busy defending his little niece or as he likes to say niece-daughter's honour point being he is very protective like right now.. it's dinner.

and lucerys had the disgusting audacity to ask you to pass him the salt, the salt directly near you and aemond did not find this amusing usually he wouldn't care maybe give a scoff but ever since someone compared insulted you directly, in-front of him and no one said a thing about it well, He was infuriated

"Get it yourself strong boy." aemond says before you even have time to react as there's an audible groan from alicent, the queen has no energy to act proper as her son's behaviour has worn her down as aemond continues to glower at lucerys as this new personality aemond has developed won't be leaving after someone called you an ugly bastard as lucerys seems taken aback, he may not have the best relationship with his uncle but to have aemond so snappy is unusual
