After graduation at Cambridge, Newt asked Amelia to marry him. He moved on to study farther for his law degree, and as they tied the knot and moved in together, Newt focused on getting licensed both in muggle law, and in wizarding law.
It was a long process, and filled with things that changed him--two of which involved his children, Luke and Mia.
He began as a defense attorney, but found that it wasn’t something that he could handle. Newt dealt with the questions that any person would ask, and found that his answers didn’t fit his job. If he knew someone was guilty, could he fight to get them off, like his bosses told him to do?
As it turned out, he couldn’t. Newt wanted more than that. He quit his job, opened up his own little firm, and started to build up from there.
That is, until a man by the name of Ted, who knew Newt from the cases he’d taken at the Ministry, told him that he wanted to speak to him. Newt invited him home, and as they sat down, Ted asked him to do something that Newt immediately turned down.
It wasn’t so easy. Through his own logic, and the logic Ted and his wife presented him, Newt knew that this was really something that he couldn’t say no to. He was needed, just like he was needed before. And while Newt didn’t think that he had it in him, everyone around him seemed to think he did. In fact, the country as a whole seemed to think he did.
Becoming Minister of Magic was the last step in Newt’s realizing he really could do anything he wanted, no matter what anyone (even himself) said otherwise.
