When Sam went missing and David called the Virginia Department of Social Services. He claimed (truthfully) that he is a professor at Oxford University and is doing a background check on her.

The Administrator later called back saying that David had left the assistant in tears.
After Sam stolen the file cabinet key from Susan, the Dean's assistant, Sam asked her if she has a spare key. Susan said it's in her apartment. Sam smugly said, "Well it sucks." To which Susan replied dryly, "Yes. It even blows." in a very accusing tone.
