Stage Entry
Initial "Patrick told me that Celestin's been acting very strange lately, and it sounds like it's more than just his imagination. I agreed to look into Celestin's behavior without arousing his suspicions. First stop: the upper class dormitory.
1 After speaking with Lotte:
  • I visited the upper class dormitory, but Celestin was nowhere to be found. When I asked Lotte, she told me to collect something from Sharon.
2 After speaking with Sharon:
  • Sharon told me that's she'd made too much food and Celestin had come to collect some. He also mentioned he'd be stopping by Kirsche's later, so let's meet him there.
3 After finding Celestin:
  • I found Celestin at Kirsche's. After a brief discussion about Patrick, he challenged me to a little card game.
4 After winning the card game:
  • After I won, he shared some of the reasons for his recent behavior with me. I should pass them on to Patrick.
5 After returning to Patrick:
  • I told Patrick everything I learned from Celestin.
