Claudia could have an emotional arc centered around self - doubt. Maybe she fails at a crucial task in the Warehouse, like protecting a very important artifact. The 'hurt' of this failure could make her question her abilities and skills. However, through the support of her friends in the Warehouse 13 team, she could gradually regain her confidence and come back stronger.
