Huh? They explained a ton of shit last season and in the opener, and if what the producers say is true, they're moving more into "explaining" mode than "asking."
Heh, while they might be explaining somethings with the time travel...they aren't laying it out there easily!
So many new angles, even small things such as: Maybe Dr. Candle got stuck going in time at some point, ran into those British solders, and they cut off his hand (just like they were about to do with Juliet). Then somehow came back, and finished that one video for the Swan (with the fake arm)!!
Might not be the case, but...who the fuck knows!
