I watched the episode "The Incident, Part 1 & 2" and laughed at the lines:
LOCKE: Can I ask you a question?
BEN: I'm a Pisces.
But this doesn't make add up. The episode "Man Behind the Curtain" the whole episode focuses on Ben's birthday, which is sometime in December. In the next episode (which is the day after Ben's birthday) Jack says that they have been there fir 90 days, the day before would be day 89. 89 days after September 22 (saying day 1 is the 22nd) is December 19th. But as stated in "The Incident, Part 1 & 2" Ben says that he is a Pisces. In order to be a Pisces he had to have been born between February 19th- March 20th.
My question is in "The Incident, Part 1 & 2" did Ben just say anything to John, or did the LOST Producers not do their homework on this one?
