[@AtomicNut] Soma has a very limited amount of knowledge on magical girls the only dark one being her sister who was solo and she never met a light who was paired or working with another, so in her mind being a magical girl is the truest embodiment of freedom, free from conviction, duty, cages etc. She'll lay down her life to save one person without thinking about it but it's her choice to do so she wants to save and help people its not a job or a duty to her. This all being said seeing magical girls huddled up together like their sharing a campfire kinda walks all over that freedom ideal to her.
