In this episode, Murphy implies that McManus is around 48 years old, but he can't be. In "A Game of Checkers" (the riot episode in the first season), McManus tells Said that he was 10 when the Attica prison riot happened. Attica happened in 1971, so when the Oz riot happened (1997), McManus had to be 36. Even with all the years that have passed in the series (1997-2003), McManus could never be around 48. His maximum age would have to be 42.
