We know when season six of Lost will debut: February 2.

Now, thanks to E! News, we have an idea of what will take place on the most anticipated two hours of TV in 2010 (until the Lost series finale, that is).

Sources confirm to that site that the season premiere will present viewers with a pair of seemingly impossible, dueling storylines:

1. We discover that Juliette is actually alive, during the same time period in which we previously saw her...
2. ... and we see Flight 815 again.

These contrasting story/time lines will reportedly take place in different decades and continue throughout the beginning of season six.

Everyone got it? Neither do we. Everyone psyched beyond belief for Lost? So are we.
