1. **Emotional Suppression**: The character seems to have difficulty expressing their emotions outwardly, often presenting a "poker face" or appearing emotionless, even in the face of tragic events. This could be a coping mechanism or a sign of emotional detachment. 2. **Introversion**: The character has transitioned from being more extroverted to becoming more introverted, preferring to stay to themselves and spend time alone, especially in quiet or dark environments.
