One possible plot twist could be that the daughter discovers a long - hidden secret about her biological parents that changes her relationship with her adopted father. Maybe she finds out that her mother was forced to give her up and her husband knew more about it than he let on.
A third plot twist could be that external forces try to disrupt the adoption. Maybe there are some legal issues that come up, like a claim from another family member who wants to adopt the daughter instead. Or society's views and prejudices start to play a role, causing problems for the family.
Another plot twist might be that the husband has an ulterior motive for adopting the daughter. For example, he could be trying to win over the mother in a very strange way. Or perhaps he is related to the daughter in a way that no one expected, like being a long - lost relative who wants to make up for lost time by legally adopting her.
For the daughter, you can start by showing her initial confusion and fear about being adopted by her mother's husband. As the story progresses, she could grow to trust and love him. For example, she might have nightmares at first about the change in her family situation, but then slowly start to see him as a real father figure.
One possible plot twist could be that Peter's real identity as Spider - Man is revealed to Tony in a very unexpected way. Maybe during a fight against a common enemy, Peter's powers malfunction and he has to expose his identity to save Tony. Another could be that Tony's enemies try to use Peter against him once they find out about the adoption. For example, they kidnap Peter to blackmail Tony into giving up some important technology.
One possible plot twist could be that it was all a misunderstanding or a magical prank.

Maybe the father turns out to have been misled in the past life and his actions were not as malicious as they seemed.
One possible plot twist could be that the daughter of death is initially thought to be on the side of evil but is actually a key to saving the wizarding world. Another could be that she has a secret connection to a major character from the original series that changes everything. Maybe she's related to Dumbledore in some way.
A third plot twist could be that the attack is a diversion. While Clary is fighting the demon, something much more significant is happening elsewhere. Maybe a powerful artifact is being stolen or a key location is being infiltrated, and by the time she realizes it, she has to race against time to stop the real danger.
A plot twist could be that the one who actually helps Judy get reinstated has ulterior motives. For instance, a politician might want Judy back in the force so that they can use her popularity for their own gain. But Judy slowly realizes this as she gets back to work and has to figure out how to deal with this new situation without losing her job again.
Love and loss could be themes. There might be relationships that are affected by the twists in the character's life. They could lose someone they love or find new love in unexpected ways. Also, the theme of fate or destiny could be present. The twists could be seen as events that are meant to happen, guiding the character's life in a certain direction.
Maybe the reason he was turned into a kid is related to a long - forgotten alchemy experiment.
