Day 3: 7:00 A.M.-8:00 A.M. - S3-E19
Continuity mistake: When Kim is working undercover, dressed up in Saunder's daughter's clothes, she comes out of the Ladies' toilets wearing brown trainers. As she sits down at the library computer, you see she is wearing her very high heeled shoes. A few seconds later, as she is walking between the library shelves, she is wearing brown trainers.
Answer: This is unintentional and a simple continuity mistake.
