- Everything about Rigaud. He's so over-the-top he should be ridiculous. Instead he's absolutely terrifying.
- In the 2008 series, during Arthur's stay in the Marshalsea he falls asleep and wakes up... to find Rigaud in the room with him. It's never explained how Rigaud got in there, since it was after the prison was locked up for the night. The obvious conclusion is that he came in during the day, then stayed the whole night and went out in the morning. Which means a murderer was on the loose in the Marshalsea all night long.
- In the same scene, Arthur tries to force Rigaud to tell him what he knows about the Clennams' secret, and Rigaud holds a piece of broken glass at Arthur's throat.
