When Shadow's body vanished Mina got on her feet and murmured a goodbye to the bird, a sad expression on her face, but her eyes blazing with anger. She went to her trailer and tried to relax, tried to collect her thoughts and calm down. Her efforts failed though and moments later items were thrown about in her room. Glasses and vases were broken against the wall, her table was broken in half with a swing of her bony tail. 
After most of her items were broken she felt a whole lot better and calmed down. She walked out of the carriage and towards where the high father was, knocking on the door and walking in.
