The summary is inside because it's too long. :/ Also, my first language isn't english, so I don't know how the story will turn out, so I appreciate the comments.

This is a what if, okay! What if Remus Lupin has an older brother and what if Remus Lupin wasn't a Marauders; instead it was his older brother. What if he went to Hogwarts as the same year as Tonks. Further summary inside, but I'll keep on going here. This is just a experimemt and entertainment for everybody.
