The thief didn't do anything about what was happening. She could only hear the mumbling. She knew it could prove to be dangerous which is why she hid as far away as she could get. The doors didn't open, and so she would simply wait in hiding. Afterwards, depending on what happens, she might leave for good. It proved a nice distraction away from what she said, which likely went over those ponies heads. Perhaps she could leave for good, and go onto her original plans. After all, she didn't really need anyone.
