4. Explore Milner's Past
Mr Rabbit, we can't help but be a little curious into the background of this MI5 senior operative who has been playing our heroes all along. Ever since her explosive introduction into the series as a spy on our heroes' side, Milner was always treading the line between an anti-hero and a guardian angel, so the reveal that she's been the Big Bad all along, is rather impressive. What we really need though is for the show to dig deep into Milner's past, showing how she became involved with Corvadt and Janus. Best of all, I reckon that following the commercial and critical success of the first season, we could even get stretched to seeing the moment when 'Mr Rabbit' snaps and kills her torturers in a bloody, thrilling opening.
