Sister-In-Law

"Belle, I need to go back and talk to my brother," Trixie said anxiously to Belle who was now driving. Trixie was too shocked earlier when she saw Belle, especially the way she talked to Arthur, that she wasn't able to stop Belle when she dragged her away from her brother.

  Trixie had never seen her best friend like that before. Belle was so cold earlier. It was the side of Belle that she hadn't seen before but her brother knew very well.

"No," Belle instantly replied. "I don't know how you anger your brother but that look on his face indicates that you two won't be able to talk properly. He needs to cool down first," She added as she continued to drive. 

Although Belle and Arthur both went to the headquarters of the Twelve Army that morning at the same time, they took separate cars because Belle will be going back to The Ellington later on. She just needs to drop by J's office to talk something about The Ellington.
