"It looks like your cousin finally realized how overconfident she was before. It's a good start."
Sam told that to Maria. Maria agrees with him as this is true. Previously when she got eliminated from the dungeon, she was so angry that she almost stopped eating for one day.
Fortunately, Maria was able to pursue her to calm down. Well for Jennifer this would be the first time face defeat like this. This really gave her a huge blow, it also helped her to understand that she was really overconfident.
Jennifer even asks Maria to help her in training. Even though Maria wanted to help in this matter, she is not a fighter.
Maria is a medical Warrior and with this she would not be able to guide Jennifer. She already told Jennifer to search for a good teacher, but it looks like Jennifer did not have any interest in becoming a student of another teacher.
