The loss of Lucifer from the dome was a huge blow to Trixie and she'd been sulking since it happened. Even going to stay with Castiel and Balthazar didn't pull her out of her funk, especially since she knew it was because there was weird stuff happening and her mom was worried about her. Sure, her uncles spoiled her rotten, but they were also clearly distracted by whatever was happening so it wasn't quite the same.
Finding out that her dad was here did the trick though. Trixie bugged the angels to take her to the bakery and then home so she could have chocolate cake with her dad. They made her clean up and pack her things first, which got them a lot of eyerolling, but when she finally got home, she dropped her bag inside the door and ran to find Dan. "Daddy! I'm so glad you're here!" She carefully set the cake down and then wrapped her arms around him.
