Season Two consists of 23 consistently entertaining episodes, its a Great series.
While some are stand-alone in nature, the serialized structure of this year's main story arcs really provide the show with renewed focus and purpose.
Season 2 is faster in pace and almost breathtaking in terms of plot.
Some of the characters' backstories have been revealed, unfortunately not Birkhoff's :-(
Dont want to give too much away - but this si a great watch.
