I realize now that I just don't have the mental bandwidth to write an entire fic, but I do still want to inflict my HammerHedgeAnvil idea upon you all.
((Part 1 of The Flea Bottom Tour))
It begins like this: Baelor lives! And by virtue of Dunk swearing himself to Baelor before he keels over, he is extremely attached to Dunk now. Practically begs Dunk to come back to Kings Landing as his sworn sword.
Dunk is very good at his job! If you are a Targaryen within his sight, you are the safest person on the planet. Matarys attaches himself to the hedgeknight Egg style (because he's only a year or so older than Egg in my dululu land) and now Dunk has two princelings following him around like ducklings.
Maekar (who has followed them to KL instead of going to Summerhall, he just can't let Baelor out of his sight rn) has BIG FEELINGS about all of this. His favorite brother (the brother he has not-brotherly feelings for that he is trying desperately to ignore but just Can't) is now never without this stupid fucking hedgeknight. The same knight that beat the tar out of his own son. And it was deserved!! He's grappling with the reality that Aerion is a little fucking Monster and will not stop trying to hurt others. He raised that! MAEKAR made that monster. And Baelor (and Egg he discovers later ((trigger warning, child SA))) paid the price.
And the one who is protecting his family from Aerion (from Maekar) and the vipers of the court is both competent and kind, like his beloved brother is. They're two peas in a pod, Baelor and Dunk. Ser Duncan may not have the silver tongue Baelor has (quite the opposite most times), but he's honorable, righteous and ferociously protective.
And Dunk's so so soft with the young ones. (Headcannon that Maekar turns into the gooiest, most dotting softy around babies/young children)
And that kindness, that chivalry, it extends to Maekar too! Dunk DEFENDS him, saying of course you fought for your child. That's what a good father does. And it tears strips off of him every time, because if he was a good father, Aerion wouldn't be the way he is, and Aegon wouldn't have attached himself so thoroughly to Dunk. Baelor wouldn't have had to fight and almost die for a hedgeknight's (for their family's) honor.
So Maekars extra prickly, trying simultaneously to watch over and keep his distance from Baelor, and finding himself to be loathsome in comparison to a hedgeknight. While also developing feelings for said hedgeknight and trying (failing) to squash feelings for his brother.
Now here comes the inciting incident of the would-be fic that I can't quite figure out, and don't really want to because I'm tired and this is for fun. Somehow, someway, by conspiracy and treachery, Maekar is lured out of the keep to be assassinated. To undermine Baelor somehow, throw the Targs into chaos or something. Dunk shows up and saves him, because he's got a pretty vast network of informants by now, sweet personable man that he is, and he's the only knight/guard who even wanted to save Maekar (he's been extra lately, no one but family wants to deal with him rn).
So it's like 7 vs 1, Dunk vs Traitors, with Maekar a little roughed up already trying to figure out how to help Dunk, but he's half slumped against a wall or some shit.
Que @raethereptile 's idea of Dunk absolutely WRECKING SHOP, holding nothing back because he's so outnumbered (and also because there is Maekar, usually so big and loud and angry and flawlessly clothed, now small and scared. How dare they. HOW DARE they touch Dunk's family)
