There's not enough information to say exactly who Hailey is. She could be an ordinary person who wants to share her story, or she might be a public figure in a certain community or field.
Another theme is family relationships. Fanfics often look at how Alex interacts with her family members in different situations outside of what we see in the show. For example, how she might handle a family crisis while away at college. It gives more depth to her family - oriented side.
Sure. There are stories where Alex Dunphy participates in science fairs. Her dedication to her projects and the challenges she faces while preparing for them are great stories. Also, the interactions she has with her siblings during family vacations are quite interesting and can be considered appropriate stories.
I'm not sure who specifically 'Chris Hailey' is without more context. There could be many people with this name. Maybe it's a relatively unknown individual in a specific community or field.
One common theme could be self - discovery. Luke exploring his sexual orientation and coming to terms with being gay. Another might be relationships, like his first gay relationship and the challenges and joys that come with it.
Some fan fictions might focus on Luke's relationships. For example, a story about his friendship with a new neighbor who is a bit of an outcast. Luke helps the neighbor fit in and they have all sorts of fun and heartwarming experiences together.
A memorable moment was when Claire had to deal with her daughter starting to date. She was overprotective and it led to some really hilarious scenes as she tried to spy on her daughter's dates. It was a classic Claire moment, showing her motherly instincts gone a bit overboard.
There's a fanfic called 'Alex and Her Hidden Talents'. In this story, Alex discovers a talent she never knew she had, like painting, and it shows how she balances this new discovery with her academic pursuits. It's really interesting as it gives a new dimension to her character.
