Why do boiled eggs smell but scrambled eggs don't?

This question was posed by a friend and I don't know the answer. She's curious about the smell when you finish cooking eggs by the different methods. I think she may not be able to smell scrambled eggs because of how often she eats them. Please correct me!

Boiled eggs smell because sulphur compounds in the proteins making up the egg white release hydrogen sulphide when heated to 100 C. When making scrambled eggs (1) the temperature is usually less than 100 C and (2) compounds in the egg yolk (which is kept separate when boiling) react with any hydrogen sulphide thus neutralising any smell.
