There, she meets Marty McFly and they have to work together to fix the time rift that her experiment created.

A plot could involve a group of students starting a secret club within Hogwarts that focuses on exploring the Forbidden Forest in a more in - depth and safe way.

He might struggle with basic Muggle things like using a calculator or writing with a pen instead of a quill.

This would create a lot of humorous and heartwarming situations as he tries to fit in.
