About Charlotte showing on the yatch. Even if she's affraid and all, I tend to belive she's not the top model for nothing. She's a professional. And she can show the fangs and who's the queen if needed. Plus, we see she's affraid. She focused, not calm and confident. She's on a defense stance. But she witnessed the fact Kaylah tried to outstand her. Lucy pointed it as well. She want to give a lesson. As Kaylah said to Emma "none can beat her, we'll fight when she's retired". Charlie's still have the fire, and she proves it. Beside, she's probably braver because of the good influence MC has on her
