Arianna hid successfully - In Victor's walk-in closet. She figured out that Victor's place was hardly frequented by Marcel and for very good reasons. Who in the world loves all? Him, Victor.
Hence, she hid in his closet for over an hour and came upon a piece of disturbing news in the end.
"How could you be so easily tricked?" Victor laughed at her.
He stumbled upon her hidden behind one of the cabinets in his closet after she nearly gave him a heart attack. And right now, they were seated in his room, and by 'they, she means Mimi's part of the party.
"Marcel tricked you," He confessed.
"What?"
And yes, that was the disturbing news.
"H-how? W-why... How could he do that to me? Did you know I was frightened? How much my heart skipped a beat when I thought of him finding me and keeping true to his threat!" Arianna was flustered, her hands on her chest.
