I'm not that familiar with her, but she must be the central figure in this story. Maybe she was someone who went through an extraordinary event related to judgment.
One great 'NCIS LA and NCIS Crossover Fanfiction' is 'The Joint Operation'. It combines the unique characters from both shows really well. The plot usually involves a case that requires the expertise of both teams. It shows how the agents from NCIS and NCIS LA interact, like how Gibbs' no - nonsense approach clashes and also gels with Hetty's more mysterious style of leadership.
Well, in a story like 'Ellie's Story: A Dog's Purpose Novel', apart from Ellie, the main characters could be the people she lives with. They would be the ones who take care of her, train her, and form a deep bond with her. There might also be some antagonists, like people or animals that pose a threat to Ellie or her family. This would add conflict to the story and help in exploring Ellie's purpose further.
One reason is the expansion of the universe. By crossing over, fanfiction writers can explore new relationships between characters. They can put characters in situations that test their limits and abilities. Moreover, the fans are already attached to the characters from both shows. So when they are combined, it's like a dream come true. It gives a chance to see how the LA - based agents would handle a case that's more in the realm of the original NCIS and vice versa.
A really interesting piece of fanfiction in this crossover genre is 'Cross - Agency Tensions'. This story delves into the initial frictions between the NCIS and NCIS Los Angeles teams when they first start working together, and how they overcome them. It's a great read for those who like character - driven stories.
You could simply hand them to her directly. Make sure to have a friendly smile and say something nice like 'I thought you might enjoy these comics, Ellie!'
