Episode Guide
Note: When giving episode numbers, many fansites that I've seen (including Fox's own recent episode list) like to list the episodes in airing order and give them numbers in the style of 1X01. However, when they do this, they are creating a lot of possible confusion because the actual production numbers similarly use an "X" but the production numbers do not always match the airing order. As a result, when a site uses an "X" you often don't know whether they are giving you the production number or their own made-up number. That's why, in the list below, you'll find the actual production numbers, and then an airing order number in the simple style of 101.
