Jann is minding his own business. He is playing by himself in the courtyard with a wooden sword: this definitely constitutes minding his own business. Nothing that follows is his fault.
"It's Reko, he's not going to tell anybody. ...Unless being a duke makes you officially a grownup all of a sudden."
"Good," says Milo firmly.
The funeral proceeds funereally.
The Raxwell contingent goes home.
Jann develops a crush on the stable groom's daughter, who is four years older than him and thinks this is cute and gives him enough tidbits of attention that it's a long time in winding down. When it does wind down he promptly develops a crush on a village milkmaid, who doesn't think it's quite so cute; when he has wrested his attention away from her it is pretty clear that "Jann is fascinated by damsels" is going to be an ongoing theme.
"Well, they're - you know, damsels! I'm going to be a knight and you're already a prince, we are supposed to be interested in damsels. And rescue them from things and then kiss them, it's like a rule."
"I should see if Alirra wants to play chess or something," says Jann dreamily, Alirra being the name of a baron's daughter who is Jann's current object of affection, about the same age, and willing to indulge him some of the time.
"Yeah, but I appreciate Alirra more than you do! You can play chess with your dad."
"I mean, I guess, but if she's going to be over here I want to hang out with her," says Jann. "I like her. If anything carries her off I'm going to rescue her and then I will get to kiss her, she said if I rescue her from something for real I can have a kiss."
"Well, I haven't rescued Alirra from anything, not actually. And I don't really want something to carry her off, either," muses Jann. "If something did I'd rescue her but probably she wouldn't like it very much all together."
"I like Alirra right now. Maybe later I'll find a different girl I want to kiss who wants to kiss me."
Alirra proves unmoved by this line of argument, alas. Jann moves on to someone who doesn't need to be argued into kissing him in due course. It doesn't really make him talk about it less.
