Yes, I referred to the now-first episode as the "second pilot," which was made when the first pilot was more or less rejected. I have no idea if it fits with the series as it now stands, but it will be released as an extra feature on the Season 1 DVD/Blu-Ray.

And there will also be a 13th episode that apparently functions as an "epilogue" for the season that will/did not air in the US, but was produced for foreign markets that already had a 13-episode deal (some complicated contract shit involving the fact that the original pilot was part of the originla 13-episode budget, so they made 12 and added an extra one at half the cost, yadda yadda bullshit) - this "epilogue episode" will be on the DVD set as well.
