There has been a lot of discussion about the proper "order" for the episodes. NBC aired them out of order. Several Earth 2 fan sites have them listed differently. The index for this guide is listed in the proper viewing order based on the "Day Number" journal entries in the episodes themselves, and on the following commentary from Earth 2: Eden Advance FAQ.
Where was the episode "Natural Born Grendlers" supposed to go?
There has been a great deal of controversy about the placement of the "lost episode" called "Natural Born Grendlers". Kevin Pike, the special effects supervisor for E2, explained that the B-story for NBG - Alonzo's attempted suicide and his gradual acceptance of life on the surface - was supposed to be part of "Life Lessons". However, that sequence was cut because the episode was too long. So, the additional plot of Bess trading with the Grendler was added. Technically, NBG should fall between "Life Lessons" and "Promises, Promises". There are some clues about this placement. Namely, Alonzo has a cut on his forehead in "Promises" which he got in NBG, and the infamous "horse in a can" can be glimpsed in a distance shot of the camp in NBG. The horse was featured in "Life Lessons". However, most people place it after "Promises, Promises" because the three Gaal episodes were shown as a group.
