Request: Hmm how are the papas and cardinal when they're jealous? Like cute jealous or the annoying type of jealous? Whatever you come up with! Hope that made sense.
Answer:
General disclaimer: these qualities are not necessarily desirable in a significant other, and are simply how I imagine the characters reacting if they were to do so in a specifically negative light.
Papa I: This Emeritus brother may be the oldest, but do not get it twisted, topolino, even if he's putting a nonchalant front in public, you will hear about it later. If he catches you walking around with another guy you swear is just a friend, he'll be casual until the two of you get home. But oh, darling, you better be ready for when you two get home. You're getting spanked and not just with a hand - a paddle, but if he can't find anything, his belt works just as fine. you know the punishment, so why do you keep hanging around with other guys? because you kinda like it. Papa I is so busy, sometimes the only way to get any attention is to act out. Oh well.
Papa II: Angry jealous. Will start a fight with any other guy he sees you with (and he always wins). He trusts you, and knows you would never cheat or do anything to hurt him or break his trust, its just everybody else he doesnt trust. Thinks every other person on the planet is just dying to paw at you and get a taste the second he turns his back. if if that's not the case, he still likes to show off and defend you. if he doesnt deem the situation worth getting physical over, he'll assert dominance by walking right over to you and kissing you so passionately you think you two ought to be alone. He wants to make whoever you're with uncomfortable and also he just likes doing it.
Papa III: The youngest of the Emeritus line would only get jealous if he thought or had proof that you had feelings for someone else. Perhaps he even thinks it's kinda hot to see you with other men, even if he knows that nothing is going on. Oh but if it were, perhaps that could be hotter? He would never tell you these dark fantasies. But if he thought you were in love with someone else, or even developing romantic feelings for them? That's a no no. "Messing around and fun and games and friends are one thing, but the only person you're allowed to have feelings for is me, do you understand, tesoro?" He says with an angry voice. He puts a up a big front about it, and pretends that he can be angry, but he's really just hurt.
Cardinal Copia: Doesnt get angry, doesn't fight, none of that. He just wants to know one thing: Do you still love him? The Cardinal just gets sad and depressed. Is it something he's doing? Is he pushing you away? Do you still love him? Has he been treating you right? You have to spend the rest of the night consoling him and promising that whoever he saw you with is just a friend, and that you still love him.
