This was a good episode, but was out of continuity. The reason however, since people don't read press releases from Fox, is that this episode was originally filmed and set to air in season one. It was later buried because of episode number constraints placed on the show by Fox. The reason for fox airing the episode now is two fold; first of all, they wanted to match it up against Heroes to see how it would fare in the ratings in that time slot, and secondly because apparently some of the content of this episode will be relevant later on, possibly even this season. (Hence the twist)Kind of Ironic that the name of a buried episode aired later is "Unearthed" isn't it? Maybe not, we are talking about JJ Abrams here. This could all have been deliberate in the end......
