A third plot idea could involve Henry coming out to his best friend. His best friend could be his biggest supporter from the start and help him navigate the new world of being openly himself. They could go to pride parades together, and the friend could introduce Henry to other members of the LGBTQ+ community, which helps Henry to feel more accepted and confident in his identity.
A possible plot could be that Drizella is cursed, and Henry, being the son of Snow White and Prince Charming, has a unique connection to the magic that can break the curse. They embark on a quest to find the ingredients for a potion to break the curse. Along the way, they meet old characters from the Once Upon a Time universe who either help or hinder them. They also have to deal with their own personal issues. Drizella has to confront her past and her insecurities, while Henry has to prove himself as a hero without relying too much on his family's legacy.
Well, a plot could involve time - travel. Henry somehow gets sent back in time to when Regina was first starting to embrace her dark side. He tries to change her path by showing her the future and how she could have a loving relationship with him. Another interesting plot might be that there's a curse on Henry that makes him forget Regina, and Regina has to go through a series of trials to break the curse and make him remember their relationship. Also, they could be on a quest to find a magical artifact that can restore all the good memories of the people in Storybrooke that Regina once took away, and this journey brings them closer together.
Perhaps Henry and Ivy find an old prophecy that somehow involves them. They then set out on a journey to figure out what it means and how they can fulfill it or avoid it. Along the way, they meet different people who either help or hinder them in their quest.
One idea could be that Henry discovers a hidden part of Neverland that Peter Pan had forgotten. Maybe it holds the key to a power that can change the fate of both Neverland and Storybrooke. For example, it could be a magical spring that has the power to grant immortality or the ability to rewrite memories.
Maybe Henry and Violet start having shared dreams that seem to be premonitions of a coming danger to Storybrooke. They decide to investigate together, following clues that lead them to an ancient magic artifact. Along the way, they face challenges from an unknown villain who doesn't want them to uncover the truth.
One idea could be exploring the backstories of the lost boys in more detail. Maybe one of them has a hidden connection to a character from the outside world. Another plot could involve a new villain coming to Neverland who has a different kind of magic that challenges Peter Pan. Also, a story about Wendy's granddaughter returning to Neverland to find a lost family heirloom could be interesting.
To show character development, start with Henry being very nervous and unsure about coming out. As the story progresses, he could become more confident. For instance, at the beginning, he might stutter when trying to tell someone, but later he can speak clearly and proudly about his identity.
Another interesting plot could be Loki falling in love with a character from Once Upon a Time. Maybe he has a relationship with a princess or a powerful sorceress, and their love story is filled with magic, drama, and challenges as they come from different worlds.
One idea could be a new agent arriving at Warehouse 13 with a mysterious past that turns out to be linked to an artifact that was thought to be lost forever. This new agent might unknowingly hold the key to controlling the artifact's power, causing a stir among the existing agents as they try to figure out how to handle the situation.
A love - interest plot for Gideon would also be interesting. He could fall in love with a character from a different realm within the Once Upon a Time universe. Their relationship would be complicated by the different rules and cultures of their respective realms. They would have to overcome many obstacles, like disapproving family members or the threat of war between their two realms.
