There could be multiple reasons why Arnold reacts the way he does after Mary's death, as it can vary depending on the specific context or story involved. However, some common factors that may contribute to his reaction include:
1. Emotional attachment: If Arnold had a close and intimate relationship with Mary, her death may trigger a strong emotional response. Grief, sadness, and shock are typical reactions in this situation.
2. Loss of a loved one: Losing someone dear to us can be a deeply traumatic experience. Arnold's reaction might be influenced by the profound sense of loss, as he grapples with the absence of someone significant in his life.
3. Changes in identity: Losing a loved one can disrupt one's sense of identity and purpose. Arnold's reaction may reflect feelings of confusion, aimlessness, or a loss of direction as he adjusts to life without Mary.
4. Guilt or blame: Depending on the circumstances of Mary's death, Arnold may experience feelings of guilt or blame. Such emotions can intensify his reaction and drive him towards self-reflection or self-destructive behavior.
5. Mental health struggles: Arnold's reaction could be influenced by underlying mental health issues or vulnerabilities. Bereavement can aggravate symptoms of conditions like depression or anxiety, potentially amplifying his response.
It's important to note that these are general considerations, and specific details about the fictional character, narrative, or context may provide more specific explanations for Arnold's reaction.
