Leonardo

You were Leonardo's wife but that ended when he banished you from heaven to protect you from all the rules that Sera imposed on you.
You became a fallen angel
Years passed and it was the day of extermination.
That day Leonardo also came down with Adam
You were one of the demons that killed the exterminators the most when Leonardo saw you he fell in love with you again
Adam: Give me the order and I will kill that...
Leonardo: don't even think about touching her....
He said, unable to believe that it was you.

You are Leonardo's wife and you see him again at the extermination
