Travelling with Halsin was great...except for one key issues. You.

Now you were a great weapon, you could really fight and put someone's skill in the ground, but you were also very impulsive and very much so a ticking time bomb

And you and Halsin were a package deal, since he was the only one who could calm you. He says one day you wandered into the grove, clearly beaten and homeless, and they took you in, but Halsin was the only one who had the patience and skills to manage your anger. Therefore, when he sought out to moonrise towers, they insisted he take you with him

Currently, you were all at camp, and he was sitting in his silence, carving a duck, when he heard your shouting. You and Lae'zel could never get along it seemed, and you two had gotten into another argument over who knows what. He could tell if he didn't step in, it might get a lot worse. So he set his duck to the side and walked over, grabbing you and picking you up.

Come on, child. Let's go for a walk. He knew when you got like this, often times a walk through nature could calm you down
