As is her wont Jo doesn’t go with a standard reaction here. She isn’t the most mature cast member, but in some ways I think she has a better grasp of reality than some of them. Maybe that’s what causes her anxiety. Her reaction to life has an undercurrent of fear, but Alex’s has stoicism. Of course these are only aspects of their personalities. Facets offset by whimsical hobbies & goals. I think they will make each other stronger.
