What?! still with the knight plan. Duh, Lamia really ignoring her brother potential. Her brother can't be and don't wanna be the next duke. He loves (and great at) sword. But she really going to throw everything out of the window (with possibility ml cured his brother).
Girl you said you want the best for your bro. But no. You just want to shelter him. No sheltered kid gonna be strong. She pretend nothing happen. Even after whay her father said. Even after he made such oath. And she supposed to be "smart". Are you kidding me? *FacePalm*
