Creepy

Tom tried not to let his surprise show on his face on hearing her sudden confession. She killed someone? Bryan had said Sonia's half-brother had committed suicide because of Lucy, he hadn't mentioned anything about Lucy murdering anyone, so what was she talking about? On second thought he realized that it was possible for Sonia to withhold such information from Bryan. There was no way she could have possibly told Bryan that her best friend had murdered her half-brother. It wouldn't make sense. Or perhaps it was just her guilt speaking? That was most likely as he couldn't imagine a person like Lucy hurting a fly.

Lucy looked at Tom's face, but she couldn't tell what he was thinking as his expression was blank, so she sighed, "You don't believe me, do you?" She asked, looking at Tom.
