In the season 2 premiere of Sleepy Hollow
, Henry works to free Moloch from purgatory, Andy comes to Abbie's aid and Ichabod rescues not just one Mills sister, but two.
At the conclusion of the season 1 finale, the home team wasn't doing so well. Abbie took Katrina's place in purgatory, so Ichabod's wife, and the only witch at the ready, could help stop the Second Horseman from arising. Little did they know that they were too late. It was revealed that Henry was War, and had arisen many years prior, and also Jeremy, Katrina and Ichabod's son. In an extreme act of defiance, Henry handed his mother over to Abraham/the Headless Horseman and buried his father alive. This presented a problem for Abbie since she was basically acting as a seat filler for Katrina in Purgatory.
