A plot could involve a family from Shameless having to go through the foster care system which is where The Fosters come in. The Gallagher family's chaotic lifestyle clashes with the more structured environment of The Fosters' home. Lip could start tutoring one of the Foster kids in math and in the process, they learn about each other's family values and grow from the experience.
One idea could be that a character from 'The Fosters' attends a performing arts school like the one in 'Victorious' and gets involved in a music or drama project there. They could bring their own unique family values and experiences from 'The Fosters' into the new environment.
One idea could be exploring how the family reacts to the pregnancy. For example, the parents might have mixed feelings of joy and worry. Another could be the character's journey during the pregnancy, like dealing with school and relationships at the same time.
I think Ian from Shameless and Jude from The Fosters would make an interesting pair. Ian has his own struggles with his identity and relationships, and Jude is also on a journey of self - discovery. They could bond over their shared experiences of not always fitting in with the mainstream. They might start a support group for LGBTQ+ youth in their combined neighborhood.
A more emotional plot could be that Noah discovers Jude is being bullied at school. Noah decides to stand up for Jude in a very public and bold way. This causes a bit of a stir at school, but it also starts a conversation about bullying. Jude is initially embarrassed but then realizes how much Noah cares about him and their bond deepens as they work together to combat bullying in their school.
One idea could be to have the Gallagher family from 'Shameless' somehow end up at Hogwarts. Maybe Fiona could be mistaken for a new teacher and cause chaos in the school with her no - nonsense attitude. Another could be Lip getting involved in a magical experiment gone wrong with Hermione. He might use his street - smart knowledge to help her out in a different way than she's used to.
Another idea is that the OC is a long - lost relative of Fiona's. This would open up a whole new set of family dynamics. They could have different views on how to handle the Gallagher family's problems, and there could be a lot of conflict and resolution as they figure out their relationship and how to move forward together.
Another plot could be a character from the future coming back to the present in Shameless. They could be trying to stop a future disaster that is somehow linked to the Gallagher family. This would involve a lot of mystery and intrigue as they try to figure out what the future event is and how to prevent it while dealing with the chaos of the present - day Gallagher family.
Another plot could involve how the other characters in The Fosters react to Emma's pregnancy. For example, her friends could be super supportive, while some family members might be disappointed or worried at first. This could lead to different relationship dynamics and character growth throughout the fanfiction.
Another theme is loyalty. The characters in both shows have strong loyalties to their families and friends. In a crossover, it could be interesting to see how the loyalty of a Shameless character compares to that of a Fosters character when they are put in a situation together, like when facing an external threat or when having to make a difficult choice that affects both families.
Another interesting one could be 'Foster - Gallagher Family Values'. This fanfic delves deep into how the values of both families might merge or clash. It's really well - written as it explores the complex relationships within each family and how they would interact on a more personal and emotional level when brought together.
