Barry
Did they ever explain why Nathan started calling Simon "Barry"? They made a big point of the "name change" at the beginning of S2, but I missed the explanation if it was ever given.
shareHe called him Barry because he couldn't remember his real name. Nathan is crap at remembering names. Or making up fake names. It was shown many times in the show.
I think Simon went along with it because being called Barry was an improvement on the things Nathan used call him.
Clever things make people feel stupid and unexpected things make them feel scared
