It had been ages since the last time Pansy and Draco had had one of their "therapy" sessions, a tradition that had started back when they were children and Pansy had decided she wanted to grow up and be a head Healer. That dream had been long lost, but the practice of playing along had lasted throughout the years. She would sit and listen to his problems and, in the end, diagnose him and give him a prescription that consisted of anything from lollipops to convincing Mr. and Mrs. Malfoy to buy Draco a new broom to cure him of his "sickness."
It might have seemed a silly game to play to those who were not Pansy or Draco, but Pansy knew better. Silly or not, it always made them feel better and it was a great way to work through pressing issues and put things into perspective. It was one of those things, just like cocoa nights with Theodore, that Pansy never wanted to lose.
So, nearing midnight, Pansy made it through the gates to the manor and through the wards that Draco had taught her so that she would not run into any nasty hexes along her way. Once inside the wards, she Disapparated to the balcony outside his room and knocked on the window, peering in. He was expecting her, so she didn't worry about startling him or any of the manor residents.
