It might make them sad.
The other characters could be affected in various ways. Some might be in deep mourning, while others might feel a sense of relief if she was a difficult person. Her death could also cause changes in inheritance, which could lead to disputes or cooperation among the characters depending on their relationships.
I don't know for sure, but it could be Aunt Clara's family members like her nephews and nieces, or her neighbors who are part of the Christmas celebration.
The death of Iago has a profound impact on the other characters. The ones he deceived and wronged may experience a complex mix of emotions. There could be a sense of vengeance satisfied, but also a feeling of emptiness or even guilt for not having seen through his schemes earlier. Those who were caught in his web of lies may find it hard to fully trust again right away, but over time, his death may allow them to start rebuilding their relationships. The overall mood among the remaining characters may shift from one of suspicion and fear to one of cautious hope and a new - found determination to move forward in a more positive way.
For Stefan, if Katherine dies, it could be a huge emotional release. He has been so tangled up with her for so long. Her death might finally let him move on completely and focus more on his relationship with Elena or just find peace on his own.
Caroline would also be devastated. As Stefan's friend, she would have to deal with the loss. It could make her more determined to protect the town from any threats, as a way to honor Stefan. Bonnie might try to use her magic to bring him back, which could put her in a dangerous situation, especially if it involves dark magic. The other vampires in Mystic Falls would also feel the impact. Some might see it as an opportunity to gain more power, while others might fear for their own safety as the power balance in the town shifts.
For Bonnie, Elena's death could be a huge blow. Since they are best friends, Bonnie might be consumed by grief and use her magic in dangerous ways, either trying to bring Elena back or lashing out at those she blames. Caroline would also be devastated. She would probably try to keep the group together in the face of this tragedy, but also struggle with her own sadness. And for the other characters in Mystic Falls, Elena's death could change the power dynamics. Some might see it as an opportunity to gain more control, while others would be afraid of the chaos that could follow.
Natsu would be extremely angry. He is very protective of his guildmates. Levy's death could fuel his rage and make him go on a rampage against the enemies. He might feel guilty for not being there when she needed help. As for Erza, she would take Levy's death as a sign of her own failure to safeguard the guild. She would become more strict in training the members and more vigilant in protecting the guild from future threats.
Happy, Natsu's companion, would also be very sad. He was used to Lucy being around and would miss her presence. The whole Fairy Tail guild would be in mourning. Erza, for instance, would feel a great sense of loss as Lucy was like a little sister to her. This could lead to changes in the guild's dynamics, with some members becoming more withdrawn while others might try to be stronger to honor Lucy's memory.
For Raphtalia, Naofumi's death could lead her to question everything she has believed in. She might even turn against the world that let him die. She could start a journey of self - discovery while also trying to keep his legacy alive. Filo may go on a rampage in her grief, attacking those she perceives as enemies without discrimination. As for the other heroes, they may start to realize the true value of Naofumi only after his death. They could try to make amends for their past actions, but it may be too late. His death could also cause political unrest in the world of the series. The people who supported Naofumi may rise up against those who they think are responsible for his death.
Well, her death at this time of the story might change the power dynamics in a family. Maybe she was the matriarch and now there's a struggle for who takes over her role. Also, it could lead to secrets being revealed if she was the keeper of some family secrets. And perhaps her death is a catalyst for some characters to re - evaluate their own lives.
Well, for Lucy, she would feel like she lost a part of herself. Natsu was always there for her, and his death would leave a huge void. Gray, who has been Natsu's rival and friend, would have his world shaken. He might even question his own strength and purpose. Erza would be in deep pain, but she would also try to hold the guild together. The younger members of Fairy Tail would look at Natsu's death as a great loss and it could change their view of the guild's missions. They would become more cautious or more determined depending on their personalities. Overall, the guild's dynamic would be severely disrupted.
