Christmas comes to Star City in the first official images released from next week's Arrow midseason finale, titled "Dark Waters."

Damien Darhk will launch an attack on Oliver Queen's holiday party, and when Oliver -- who recently dedicated himself to fighting H.I.V.E. out in the open -- makes a move against the organization, Darhk will "retaliate in a brutal manner."

Could this play into who ends up in that mysterious gravesite? Only one way to find out. Check out the images and official synopsis below.
