"What do you think about me fighting? I know that we haven't really had and y proper sparring matches. But I want to hear what you think of me now so I can work on improving before I fight our classmates." Maria was dead set on getting stronger and not being the weak healing student that most would expect from her.
"I think you are going to surprise them. You don't look strong or fast. You are much faster than they will expect and you can use close combat dagger techniques too. With Lit to heal you, I bet that you can endure tougher situations than you even know."
The theory that Clark had was simple. Lit was able to heal others with a touch. Since Lit had gotten stronger and grown in to a princess jellyfish. She was able to heal even better than before. That meant that she could push Maria further in a battle than Maria's body would normally allow. It was a sneaky tactic, but a powerful one.
