Hazel (Edgar in the British version) is a character appearing in Professor Layton and the Unwound Future. He is easily scared, especially when he sees Layton (thinking he is the evil Future Layton). He also makes a comment on Lukes stare when Layton is looking for Luke. Hazel is one of the first residents of Future London and also gives Layton the Mystery: Scared People. He is secretly in love with Becky. He wants Luke's parrot to deliver something for her too.
Hazel doesn't give any puzzles to Layton and Luke. This means there is no need to talk to him if you're scavenging for lost puzzles.
