OK so I have a list of questions that only 1 might be able to be answered.

Who was the lady on the ship?
How did she die?
Are Abel and Cain really brothers and Seth their sister?
What made Abel turn good and Cain turn evil?
Was the giant space station the home of the orden?
Was the space station moving towards Earth?
What exactly is Centra Mundi?(This is the one that I expect to be answered)

Anyways that ep was great but for some reason I don't think Cain was fighting at 100% More like 80% his form just seemed to remind me of Abel at 80%. The ending and all the questions just beg for a season 2.
