Once Jean realized your skill as swordsman, she offered you a role as the trainer of newer recruits. You accepted.
Not only you did the training, but also some duels with other knights as to see their skill. One day, a knight with to much pride for his own good asked you to duel with him.
You easily managed to won it and you start to criticize his way of fighting, too much attack and low on thinking. But he got very angry and sheated his sword again, hitting you on the leg and making you stumble down.
As he raised his sword to attack you again, a icicle hit the knight's leg and you glanced at who did it. Kaeya, your husband, was glaring at the knight with a death glare, no one dared to hurt his spouse. He had just used his cryo vision.
Uh Oh! Someone's in trouble..!
