Because I love it so much, how would each king react to their duke getting sick? Would they try to take care of them for a while or would they try to run the kingdom by themselves to prove they could function without their duke and make said duke proud?
Spades
Rouxls would over exaggerate his illness. Spades would want to go to work but Rouxls asks him to do a lot of things for him just so he can stay longer. He denies doing it, though.
Diamonds
Rulex is the type to take the sick day as an advantage to slack off and play games all day. He used Diamonds' old video games (like really old) and he sucks at it but he's having fun. Diamonds, when he has free time, visits him because he's a true bro.
Clubs
Rcuuls likes getting sick, actually. He just stays in bed all day and sleeps. But when he asks the Kings for favors, they over do it. Like a lot. Seriously he asks for something fluffy and they bring him big stuffed bunnies.
Hearts
And Ruullse.... Ruullse is just baby. He gets sick a lot and gets really sad to see that he doesn't get to work. He feels slightly incompetent, that's why. Hearts is also baby. They're both baby. Hearts depended on him too much and visits him to ask him how to do stuff
