Oliver Battles HIVE on Tonight's Midseason Finale of 'Arrow'

Oliver (Stephen Amell) looks really concerned in this still from tonight’s midseason finale of Arrow.

In “Dark Waters,” after the city is attacked again, Oliver makes a bold move against HIVE.

Malcolm (John Barrowman) checks in on Thea (Willa Holland) and leaves her with a warning.

Things take a horrible turn when Damien Darhk (Neal McDonough) retaliates in a brutal manner at Oliver’s mayoral holiday party.

Arrow airs TONIGHT, December 9 @ 8PM on The CW!
