how do you write the death of a really good character?
It's all up of the character and how you see their views, what view the death is coming from, how the personalities are of everyone is around the person who is dieing. x'D Like a snowflake.
How do you make it dramatic?
By doing something that would be considered a grand act of honor/horror/tragic in whatever setting in the story. (Like if it was a human, saving someone, planecrash.) or something completely out of place for said character like the character is completely stable and a hero then they discover a villian who killed their little sibling or something and they seem to recover after crying or getting angry but decide to kill themselves or something after losing it really. (LOL)
Quick you have ten minutes to write the death scene of your favorite character Tris!
I'm eating dinner. Oh no it's too delicious! -will write afterwards.-
