"Well you've been a fool!" Thorin snapped at her. "You've risked yourself, and in doing so you put others at risk too! And if you're going to continue being so reckless then I'm sorry Serena but you are too dangerous to have in our company, I will not risk the lives of my kin because of your reckless behaviour." the dwarf said to her as he looked at her sternly. "You have nothing left to prove, and yet you continue to throw yourself carelessly into danger! If it carries on we would be better, safer, if you stayed out of it and didn't help us. As much as I appreciate your assistance, I have the lives of many others to consider as well as my own." Thorin's expression softened slightly as he finished explaining, as angry as he was at what she had done he couldn't hold it against her permanently.
