The TwinSister of Harry tries to hold herself hidden from everyone. Nobody knows about her, except the Dursley's. She goes to school with Harry but just act like friends. She meets Ron and really likes him.
When Harry and Draco return to school for their eighth year, neither imagined they would be best friends.
Yet, just minutes into the train ride, Harry is diving into a near-empty compartment for protection. A near-empty compartment with Draco Malfoy sat in it.
When Ron and Hermione find him, raised voices end in a joke that never seems to leave the unlikely pair.
