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.
"Yeah. His dad can win, Reko - duke of Ferdinandia, technically no relation if I recall right - can win, I think that's it."
"I'll give it my best," he says, grinning. Jann has no way of knowing this, but it is the same grin he grinned when he asked how many instructors he would have to beat in practice duels before they'd let him into the school two years before the normal age with no money, no disclosed lineage, and no recommendations.
"And here's the dormitories. Your cohort's going to be down that hall, they don't assign rooms, just pick one that nobody's in and it's all yours. I'm upstairs, third on the right, if you have any questions you want to bring to your, what's my formal title, mentor? I will also be upstairs if you do not."
He is very, very good at nearly everything they teach here. His worst subjects are etiquette and equitation, but only in comparison to his astronomical talent at all the martial disciplines; he's still in the top third of both.
Milo, for his part, sends letters to Jann more frequently when he's exchanging chess moves with Glynn as fast as the couriers will carry them. He is impressed with Glynn's chess ability, although to no one's surprise Milo still wins their first game.
Jann is supportive of his, wosscalled, mentee! Yay! And it is good that Milo has a willing chess victim.
Glynn has been playing chess with Milo for a month and a half (and has known Jann for only a few days longer than that) when he knocks excitedly on Jann's door one afternoon.
"Jann, Jann, guess what I did!"
"Rescued a damsel? Thwacked a teacher? Rode the big black horse for a league without getting bitten?"
"Wow! That's even more impressive. This is what, your second game, now? He will have you in his castle to play chess with come fire or flood."
"Hopefully there will be no fire or flood. That would interfere with playing chess."
"If anything is on fire that should not be on fire, I would rather deal with it before playing any chess."
"I should go catch up on my correspondence, if Milo has even noticed that you give him a close game I'm probably already supposed to bring you home with me."
Indeed, when the term ends Jann brings Glynn home with him.
"Hi, Milo!" he says when he has located Milo. "This is Glynn, your chess nemesis. Glynn, this is Milo, my cousin." Glynn has already been briefed on "be careful not to break him, he's under a faerie curse".
