Hogwarts, Hogsmeade or Diagon Alley
Adrian sat at one end of the Slytherin table, it was the last meal he'd ever have at Hogwarts and his one true love was sitting at the other end. He chanced a glance at her and saw she was watching him too, he couldn't ascertain her facial expression but by the way that Daphne was holding Tracey in her arms she seemed to be upset. Adrian had told her that he was to marry, and Tracey hadn't been able to hold back the tears and she had seldom stopped crying ever since. Adrian didn't know what to do, he wanted to talk to her but she didn't respond. So he had eventually told himself that she wasn't worth it, he would marry and be happy with his new wife.
The third lie was to himself.
